iCloud Settings crash every time on iPhone, iPad and Mac
Since yesterday, clicking iCloud in Settings on my iPhone, iPad Mini 2 and on my MacBook Pro 15" wRD crashes the Settings app.
Maybe it has something to do with iOS 9.3, but the iPad mini is not yet upgraded but it still crashes. On iPhone and iPad, when I click iCloud inside the Settings app, the Settings app just closes and I'm dumped back to home screen. On the MacBook, I get "There was an error in iCloud preferences." and that's it.
When i go to icloud.com and click Numbers, I get dumped back to the log on page. When I click iCloud Drive I get "Can't load iCloud Drive" and "There was a problem loading your data for this application". I clicked Report a few times but nothing got resolved.
When i click Notes on iCloud.com, I get an error message saying "Notes has stopped responding." with "An error has prevented this application from working properly. Help Apple improve its products by sending us diagnostic and usage information about iCloud." What's interesting is that in the report field I see the error message "CloudKit error - access denied" - "_reason" : "private db access disabled for this account".. wierd.
Has anyone seen this problem - how do I solve it? It looks like my iCloud account data got corrupted suddently. I use iCloud for Notes, Reminders, Bookmarks and Calendars, so that I can share those between these 3 devices.
Thanks.
iPhone 6, iOS 9.3, iPad mini 2, MacBook Pro wRD
