As a dev I’d be absolutely embarrassed if I released a version containing so many regressions and failures in functionality.
As someone who very recently purchased a lifetime plex pass subscription, I’m annoyed and disappointed.
Personally I think the response should be an apology and a forced downgrade to the previous version until at least the big issues are resolved. Paying customers shouldn’t be expected to test new versions unless they opt in.
I have manually downgraded to the Android 10.26.0 (available here: Plex for Android - #525 by PlexAndroidReleaser) which works really well unlike the new version.
