C4 Rooms don't show up as rooms AKA groups in Alexa.. the commands however do exist.
On the c4 customer Alexa page you can click on the link shown in the image below and it gives you the list of commands you can tell Alexa to talk to C4. Those Rooms if built out correctly with the lights and AV devices in it in your C4 project should all turn off by issuing the command in the list to turn off the room.

I mean if what you did works for you that's great but just wanted to help clarify the conversation for others and how it should be working.. and is working for me.

Much better! So glad to have this working again! Thank you!

@DIEHARD The Alexa driver team let me know they verified the issue you reported and are working on a fix for it.  Thanks again for the detailed write up.

I would agree the only real issues I have had with Alexa started about a year ago too. The having to repeat every command to even turn something off or on and at random have it do the action after Alexa already said the device was not responding and the more recent can’t talk to null is what drove me to give 3.3 a whirl.
I get the interacting with the cloud and the delay.. and I am even accepting it will exist. But for just basic lighting on/off/dim functionally it does hurt my heart a bit when the cheep Chinese cloud based non-c4 smart devices I have in my closets react 10x faster and more reliably than a professional system to the same commands over the internet via Alexa.
I am hopeful again though as with this last update the lights are being much more responsive… even if much of my media functionally is currently missing.

DVD proxy issue was confirmed and they are working to fix it now.

I'm having similar problems, though more selective.
I have multiple virtual Devices for my Theater (Netflix, Amazon, HBO Max, Hulu, etc.) so I can turn any on with Voice Commands. I've used these for years. Most of these are still working, but for some bizarre reason, neither of the Bluray Player players are being recognized. When I log into my Alexa account, they are listed there as devices, but strangely when I log into my.control4.com they're not (while all the others are listed). They have been there in the past, since I have been using them for several years, customized the name, etc.
I have tried multiple things to get this working:
Reboot Controller Reboot the Echo dot I'm using Unlinked the Control4 Skill in the Alexa interface, rebooted the Controller again, and then relinked Rediscovered devices through Alexa multiple times Cleared the cache on the Alexa App, checked for updates (last update was June 1) I even removed one of these bluray devices in the Alexa app, hoping that it would be 'rediscovered', but no joy. It's now nowhere to be seen I renamed one of the devices for the same reason, to see if that would trigger re-recognition, but also no joy The only thing that has changed is Control4's release of OS 3.30, and while I haven't yet upgraded, the release and system changes actually fixed another problem I've had for months, where Alexa would respond "Hmm..I'm having trouble reaching null" whenever I gave a voice command to turn on any of these devices (and which did in fact turn on, despite this odd error).
So no matter what I do, I can't get Alexa to respond to voice commands to activate these 2 bluray players, even though they were shown as devices in the Alexa App. And presumably because there's an issue there, my.control4.com isn't seeing them either. Very strange...

I always try not to comment on these as they get nowhere but it does build up over time so here is my 2 cents..
I don't get all this comparisons to cars... If you buy a car no matter how expensive or what brand/make/model.... the point is it's your car and you can choose to service it as you wish with a dealership or do it yourself. 
With C4 the feeling for me is I still do not "own" my system as I do not have full control of it even though it is fully purchased. EVERYONE short of many of the dealers on this forum I have ever had conversations with all refuse to use C4 for this very reason. I can't disagree. I love it and it's abilities but for the majority they are not going to even be seen as an option as there are so many more open cheaper options out there actually have wider capabilities though not being as streamlined as C4.
I did get my first hands on with C4 due to being in a new construction community. The initial year passed in the community so I put feelers out to see who was not using their gear to see if I could get more equipment. I have had 2 people in the entire neighborhood say they still had an active 4site subscription to control their Thermostat. It blew my mind to here so many say "what smart switches?" or "I wondered why those switches looked diffrent than the rest." and "I wondered what that C4 box (EA-1) was for." In the end I have more people offering to sell me EA-1's than I can fathom buying let alone using!.. And this was just "my" neighborhood. The builder did 5 neighborhoods that year all with the "smart home" package. That is so much unused equipment!
How is that helping C4? Why is that the market C4 is going for? I have no idea how this strategy is paying off other than they only need one actual "sale/install" in the neighborhood and the price is going to be so high it covers the cost of all the hardware they just threw away?? Ya I still don't get it. Also they have now flooded the market with gear that only the DIYers could find a use for anyway because with C4 it's all about selling a package/solution and don't have any model to build your system one component at a time due to having to hire someone else to add it to your system. They do not have to change their dealer model even as if you do it yourself and need help... you still need to contact a dealer.
Anyway.. we are all here because of our love/hate for C4. I do feel that giving end users full control of their system would cause way more love than hate for them. This forum is with out quesion in a silo and outside of it there is far more hate than love found for c4. Actually let them use it and I guarntee that changes!

Simply put, the system is locked down so that Control4 and its dealers can make more money. So please, let's dispel any myths about Control4 having some altruistic goal to increase the level of support for its end users. It's about the money. It's always about the money. 
Now, perhaps some dealers may feel otherwise. Perhaps, some dealers such as yourself, truly believe it is about providing the best experience to the customer. I think that's naive, but it doesn't really matter. All that matters is what Control4 thinks its dealers think. And if Control4 thinks the dealers would go crazy about opening up the system, regardless of the ultimate reason why that is, it will never open up the system. And that's a shame. Everyone could make more money if the system were open. 

But you can take your Lambo to the kid down the street. If he knows how to do the work.. He can!

I still don't get this. Sorry. I think we are talking about owning a product we can't as the owner maintain and that a dealer is required. My Porsche dealer would love me to bring it in for oil changes, but I don't have to. I can change my own oil. Ok, I have taken it in on occasion when I wanted to test drive the loaner.
With C4 I have friends that would spend the 50-100k, but wont because they can't "change the oil". 

Why do you guys go to such extreme examples when it's so very simply to agree that there are some customers that are qualified to manage their own systems and both them and c4 would benefit from permitted access?
