iCloud Drive on my iPhone and iPad turns off automatically
Hello,
I hope you all are safe and healthy.
I switched back to using apple devices after 5 years, and my first iphone being iPhone 4s. Recently I purchased an iPad Air and an Iphone XS Max and upon thoroughly checking that my backup to the iCloud Drive isn't working, I realised that my iCloud Drive on both my iPad and iPhone kept turning off automatically. When Turned on, it takes me to the next page where it says either "Cancel" or "Upgrade" of which nothing works when you click them, its just frozen.
The first thing after releasing this issue, I headed to the Apple Community search and did a few tips that was mentioned with the similar query, but nothing helped me fixed the issues.
To elaborate further, I did:
1) Logged out of Apple ID and Logged in (no result, still the iCloud Drive turns off)
2) Reset Network Settings (no result, still the iCloud Drive turns off)
3) Reset All Setting (no result, still the iCloud Drive turns off)
I am attaching a screenshot of what happens when I turn on my iCloud Drive. I have upgraded my iCloud Drive plan to 50gb, but still no luck.
