iCloud Drive Unknown Synchronization error on iPad Pro 5th Gen
When I'm trying to connect my iPad Pro 5th Gen to the iCloud Drive service some kind of unknown error happens. I'm using Icloud with 2TB storage and on my phone everything synced perfectly. Photos on iPad are synced well. Anyone encountered that? How can I fix that? My device is updated to latest version of the iPadOS which is 16.3 (20D47).
Screen attached, error translation: "Unknown error happened. Repeat your try again later."
iPad Pro, 12.9-inch, 6th Gen, Wi-Fi
