OK. Here are my issues:
* No Atmos output, no matter how hard I try. DD 7.1 at best
* Horrible audio delay (audio is perhaps 300 ms or more behind the picture) in DBV-T. This is the main reason I'm returning the TV. It's not possible to mitigate it in the receiver. (no delay in Netflix, Youtube, apps, etc...)
* HBO GO only Stereo output, same for VLC player installed from Google Play
* HBO GO unable to connect through Chromecast
* Gestures not available (in Czech Republic)
* Alexa not available (in Czech Republic)
* Chaotic and buggy UI / Menus. Especially program changing is confusing
* Intermittent system crashes
