Connecting to Cast Devices (Google Nest Mini, Google Nest Hub Max, Chromecast) simply does not work with Plexamp on my Pixel 3 running Android 11.
I can cast from any other app just fine, but plex simply does not work. When I try to connect, the loading spinner just spins, and eventually disappears.
On a device with a display (Chromecast/Nest Hub), I get a Plex screen saying “Sorry! Something went wrong”. Speakers make the sound that something was connected, but media never begins playback.
