Latest Albums returns MusicAlbum folder dtos, where the browse count/user-data
fields each cost a recursive per-album COUNT query; request it with the slim
album fields + EnableUserData=false under a dedicated latestalbums identifier,
and drop the folder fields and Overview from the played-track rows.
Album/artist downloads expand to tracks with pinned parent metadata,
aggregate progress, container deletes with reference-counted album
covers, and a Music tab on the downloads screen with fully offline
album playback. Home rows include music libraries (fixes plex hub
items being filtered to video types) and audio playlists join
download/sync rules.
Signing in triggered two back-to-back profile rebinds; the second re-added
the same Jellyfin connection, which tore down the live client and aborted
the home screen's in-flight fetches. The aborted pass was committed as
loaded-empty, flashing 'no content available' until the follow-up load
landed. Fix at the root instead of patching the sign-in window:
- addJellyfinConnection now reuses the live client when the connection is
unchanged (token, deviceId, URL set), matching the existing Plex
refreshTokensForProfile behavior; material changes still recreate it.
- Cancelled requests are classified end-to-end: the client's
treat-as-empty helpers rethrow cancellations, and the aggregation
fan-outs report cancelledServerIds alongside succeededServerIds.
- A fetch pass in which zero servers succeeded is never authoritative:
it keeps existing content instead of wiping it (also fixes the
pre-existing blanking of home/sidebar on a totally failed refresh),
stays in loading while disrupted (cancellation or binding in flight),
and only commits loaded-empty on a settled failure.
