Jellyfin server v12.0 RC2 release

[foxhollow]

RC2 breaks part of the androidtv client

I am running ubuntu 26.04 with all updates applied (nightly script)
I have been running JF for a few years and always apply latest versions
I have a large video library with nested Movie folders

example: 
/Movies  shared as "Movies"
/Movies/Group1 shared as "Group1"
/Movies/Group2 shared as "Group2"

OK: The JF web server sees the 3 libraries on the home screen and all 3 have files
OK: The Wholphin v1.0.2 android client sees all 3 folders with videos
NOT-OK: Jellyfin app v0.19.9 until recently saw everything but now the Group1 and Group2 folders are empty.

Something has changed and has broken the androidTV client from being able to see the content on those subfolders.

btw: If I search for a movie, it is found and played.  This is obviously a display issue with AndroidTV interacting with RC2
