Synced rows only ever had the Played flag set. Jellyfin computes Next Up
from LastPlayedDate on the member's own row and Continue Watching from
the resume position, so a member watching through the shared account got
the tick on each episode but their Next Up never advanced. Members are
now written the way BaseItem.MarkPlayed/MarkUnplayed write: date and
position included. Rows the old version ticked without a date are
repaired the next time the item syncs.
PlaybackFinished was also treated as an unwatched toggle. Jellyfin raises
it on every stop, not just completion (and on 10.11 PlaybackStart resets
Played to false first), so a stop halfway through on the shared account
cleared members' own watched state whenever Sync unwatched was on.
Playback-derived reasons (PlaybackFinished, PlaybackProgress,
UpdateUserData) now only ever mirror "watched"; TogglePlayed and Import
remain explicit and mirror either way. PlaybackProgress is acted on so
the tick lands as soon as the completion threshold is crossed, including
for clients that never report a stop.
