I'm told that OS 3.4.2 will be released at the end of this month. But, if you'd like to test it sooner, you can contact your dealer to get on the beta.
Hmm, it's working for me. Could you send me the app logs? Press OK on that error dialog (or just press CANCEL during connect to skip waiting for the 408a error), then go to Support -> Support Settings -> Email Logs -> Email. I'll PM you my email.
Thanks for the information! I'll link to your post in the bug, AV-9682. When I checked on it just now, it looks like there's a fix in OS 3.4.2.708662, but it isn't publicly available yet (pending the OS team's testing and release schedule). I asked when it'll be available and will let you know.
Just heard back. There is an issue with Spotify skip fwd/back not working 100% that we're looking into. I'd recommend taking it up your other issues with Control4's tech support. If that doesn't get anywhere after a week or so, I can track people down and make sure progress is made.
