I don't know if this is your problem, but there is a new way that users have to setup their doorbells now. Each person with the app has to have their own login. If you have more than one device using the same login it will not work. Every phone needs its own login now. All you need to do is simply login to my.control4.com and add some user emails and separate user logins and probably reboot. IF this is your issue....
