18 July 2023 Plex for Apple TV app 8.22 is still dung, demonstrating the same bugs as 8.21.
Can not watch current TV (without disabling current audio engine), nor play HD content.
Sound fails completely (ie, no sound whatsoever) and the scrub bar playback position UI become dysfunctional within a few minutes, typically less than three (< 3!).
“Use Old Audio Engine" set to [On] still seems to be a temporary workaround (ie, disabling current audio engine).
AV sync, as with every PMS for Mac and Apple Plex player app (macOS, iOS, tvOS) combination I’ve tried since March 2022, slips dramatically upon repositioning playback a few times, sometimes even just once.
