After I downgrade my iOS 16 to iOS 15.6 RC and Upgrade Delayed OTA to iOS 15.7.2 on iPhone SE 2020, I have problem with iCloud Drive. it's stuck on loading
This has never happened to me or anyone close to me.
It’s worth noting that if you restore from a backup after an update, you’ll need to log back into your iCloud account, and if you don’t, you obviously won’t be able to access files stored in iCloud.
