"Your password is required to enable iCloud Photo Library."
Hi.
I have been having this issue for a week. I have read countless blogs and even the Apple forum but nothing seems to be working. I keep getting an error saying that my password is required in order to have my iCloud photos synced but it is already turned on. I have already: signed in and out of my iCloud on my Mac (and my iPhone has everything turned on for the iCloud so it should sync normally); I have restarted, turned off, deleted everything, and tried to sync everything again and nothing is working. My photo gallery has been stuck in "updating" for days albeit connected to the internet and synced to my iCloud. I have used my normal wifi and my mobile hotspot to do this but the internet is not the issue as the speed of both is the same. I have attached a screenshot for prima facie proof of the happenings.
Assistance would be appreciated.
