Can't sync to iPad - 'Pending'/'Waiting for Server'/'Waiting to be Converted'



Paid up for my pass, in order to sync to my iPad Pro from a WD EX4100. Nothing happening but the above messages. They'll stream fine, but no sync happening. What's gone wrong?
Plex Server version:
Plex Client version: 12423


I have the exact situation. Upgraded to plex pass so I could sync to my iPad for journeys. But getting the same. Waiting for server and it’s been like this for 3 days and nothing is syncing. Please help!
