Using v3 build 884 with Pixel 2 on Android 11 and Samsung Galaxy 10se also with Android 11. Both devices cast perfectly to my Google Nest Mini, Google Nest Hub and Hub Max but both have long multiple pauses during playback on CCWGTV. Also works properly with an older Chromecast on my other TV.
Hope you can help because it would be awesome to be able to use Poweramp with my CCWGTV.
