iPad doesn’t sync photos with iCloud

Hi!

I have iPad Air 2, iPad OS 14.4.1, 0.8 Gt free storage.

Problem is, my iPad is not syncing photos from iCloud. I have syncing on, I’m logged in to iCloud. I have had this problem for few months now. Once I removed all the photos from my iPad and logged off from the iCloud and synced everything from the start. It worked for few weeks, but now syncing has stopped again.

I have now tried to close all the apps and reboot. It does not help. Sometimes Photos app says briefly “updating “, but nothing happens.
