Just quoting the feedback from other users from one single thread linked above.
There are quite many other threads in this and other forums with same feedback.
Because of german language from this thread i am trying to translate in english.
Translation: After downgrade to 1.20.3.3437 all channels could be found and asigned.
Translation: I am using (old) plex version 1.20.3.3437 which is working pretty good.
The only request is to get it working AGAIN.
Like it was working with older docker versions and like it is still working with windows version.
