Mobile sync stopped working

Continuing this: https://forums.plex.tv/discussion/212867/sync-no-longer-working#latest

I would really like to get syncing working again. Any help would be appreciated.

Bumppppppp

Solved this.
Under server setting, conversion was set to paused for some reason. Changed it to resume and sync started working again.
I really don’t remember explicitly touching that, but who knows…
