Hello everyone, maybe someone here is familiar with Android TVs. I have BBK 55LEX-6039/UTS2C which is running on Android 6.0. I mostly use it as PC monitor to watch movies or play casual games, but occasionally I also watch some YouTube and Twitch on the TV itself, even more rarely I use it as a TV.

Now the the issue itself. The issue is that I couldn't find a way to turn off notifications from apps like YouTube, Twitch (about new and features videos and streams) and Google Play. They just pop-up whenever they like and distract me from whatever I'm doing. There was nothing I could find on system settings or app settings to modify that behavior. Note that Android TV apps are different from normal Android apps and they don't have all the settings that normal app has.

Does anyone know a way to get rid of those notifications?
