YouTube stopped working after pressing the remote buttons
This is not unusual for this to happen on my roku ultra. Every other app streams perfectly. Only the youtube+roku ultra combination gives me this problem. Every other device on the same network plays youtube perfectly. Roku stick, phones, laptops, PC etc.... I can cast through the app with my phone or anything else as long as I don't try to control it with the remote. As soon as I do, it goes black. if you hit the home button, you can start casting/streaming directly on the youtube app again. update over and over, power cycle, hard restart, remove and re-install the app. Then you can't log in, but you can still cast to the app, just don't touch a button on the remote.
Again, this only happens on the roku ultra playing youtube. Old roku stick is fine. Wait a couple of days and suddenly it works again. This has happened half a dozen times since I have owned it
