iBooks and Notes crashing on startup I installed the iOS 11 Beta, then downgraded back to iOS 10.3.2. I restored to my iCloud backup and everything looked alright. However, I am having issues after the restore, some of which include:


Backups of Whatsapp conversations will not restore, as it thinks I am not connected to iCloud, despite being listed in iOS Settings.
iBooks and Notes crash on startup.


Any help is appreciated!

Thanks in advance

Update
After updating to iOS 11, all the probleme were solved and the all the data was restored.
Same here on an iPad, plus iCloud Drive app was saying I need to enable iCloud Drive, but it's already enabled. 

I managed to fix the iCloud Drive app problem. 


Switch off Settings->AppleId Account->iCloud->iCloud Drive
Reboot
Switch on Settings->AppleId Account->iCloud->iCloud Drive


Nor ibooks nor notes got fixed.

Any hints with ibooks and notes crashes are welcome.
