Plex App not working on XBOX Alpha Skip-Ahead

Player Version#:Latest Xbox
App says its being getting ready but says there has been an error after about 30 seconds
Have tried reinstalling App but no difference
Problem started about 1 week ago, running XBOX Alpha Skip-Ahead

Still an issue even after a few Xbox Skip Ahead Alpha version updates
Guessing the Xbox Plex player isn’t being used or tested much

Managed to get it working by Factory defaulting the Xbox Series X
I had zero problems with any games or apps but the Plex app kept failing to launch with a try again later error and code 0x80073cf6 for the last month or so despite working fine prior to that
