Hey guys - having the same issue here. Now I’m finding that waking up one of my Apple TV 4s doesn’t wake up the attached TV when I’m using the remote app on my iPhone or iPad, whereas before the tv did wake up that way. It still does wake up from my Siri remote. And, strangely, my second TV (which is also connected to an Apple TV 4) does wake up when I wake up the connected Apple TV via my remote app.
I’ve tried restarting the misbehaving Apple TV but it’s still not working. Strangely, when I put its connected Apple TV to sleep, this tv shuts off just fine. The only issue is waking up the Apple and not having the TV itself come back on...
I’ve also tried toggling on/off the option in settings to turn on the TV via the remote, but that hasn’t done anything. If anyone has any ideas I’d greatly appreciate it...if not I’ll just try wiping and reinstalling the os tomorrow. I swear this was working not too long ago...
