Well one small niggle, I had a custom script setup on Caddy that overrides how certain buckets are sorted because my users are too lazy to follow my instructions. They changed the BucketID string in some way but this more to do with me having a custom script dependant on something they don't guarantee.
Hopefully they allow admins to change a users preferences in the future but currently it has to be done at the user level. I'm sure that will be in a future update.
Bit unfortunate how this can even happen, but it's on me for not checking or taking a backup first. The config/db really contain anything important anyways, other than "watched" markers that are already out of sync for me across Emby/Jellyfin/Plex.
