The issue still persists in 6.4.6 (3127) unfortunately.
Sorry I wasn’t specific enough with the repro steps. Let’s try once again:
In Jellyfin Dashboard:
setup a library Movies A, with Folder A, containing movies
setup another library Movies B, with Folder B, containing movies
In Jellyfin Web Client:
Menu › User Settings › Home
In Home Settings, at the very bottom to Library › Automatically group content from the following folders into views such as Movies, Music and TV
And enable Movies A and Movies B folders
Relaunch the web client
In Infuse:
Navigate to the Jellyfin folder
Expected = Show Movies A and Movies B folders in this view
Actual = No folders are shown
Btw I have since found a workaround to this. Setting a Share name in each Library will show the folders as expected in Infuse. So maybe perhaps we can close this?
