I recently updated the Photoshop Lightroom CC v3.3 and now I cannot see my albums or photos any longer (see attached images)! I tried to restore the catalog from one of the previous backups but to no avail.
The cloud seems to have 4,200+ photos (see attached images). I also get the notification that the cloud storage is almost full (also see attached image).
I had this issue. Signed out of all apps, deleted and reinstalled but the issue persisted. I can also view my images on the web version. The only thing that worked was to downgrade back to 3.2.1 via the Creative Cloud App.
