LrC lost sync with cloud Uploads: None (Mobile App and Web cloud sync fine)

[Jeyell]

My LR Classic has 'lost connection' to my cloud library of synced photography. Lr iOS app imports from the camera and syncs with the cloud and is visible on lightroom.adobe.com fine. These two sync changes each way perfectly. However on Classic I receive no mobile syncs downloads nor can send updates to the cloud.

I've tried a Rebuild, rename Snyc.lrdata file to no joy. Odly Uploads in the Lr Sync Tab show 'None' despite the local sync photo location not being changed and points to the correct location. Its like LrC has lost its cloud connection. Tried a few system restarts too 😞

I've also logged-out my Adobe ID and in again and still shows no Uploads, despite both the App and Lr Web agree exactly on ~6K synced photographs. Ideas anyone?

LrC 10.4, Mac M1.

After a complete power-down of external drives and another re-boot, LrC decided to re-connect to the cloud and sync. Not all there, but goin in right direction.
