Well, this keeps getting better… I’ve now lost the ability to stop chromecasting - playback stops on the Plex Android app when I disconnect from Chromecast but the TV / device just keeps on playing no matter what I do on the app: reconnect, disconnect again, close app, force stop, nothing stops playback except using the Home app to directly stop casting on the Chromecast device. Seems like the Plex app is not sending the disconnect signal (because the Home app has no trouble disconnecting Plex, so it’s not the Chromecast).
More regressions on a regression-filled app…
