Calendar crashes after update to iOS 15.1

Hi,

Several days ago I updated my iPhone 12 to latest iOS 15.1 and what right after the update my Calendar app started freezing and sometimes crashing.

After multiple attempts to solve the issue by the Apple support the problem is still there.

Following suggestion of the apple advisors I did the following:

hard restart (+,-, side button)
reseting all setting
deleting all data and restore from iCloud back up
deleting the Calendar app and reinstaling from App Store

The problem was gone only when I restored my iPhone via finder on my MacBook Pro.

However, right after I restored my iPhone from iCloud backup the problem was back again.

During last call with Apple, the advisor suggested that perhaps screen of my iPhone is somehow damaged, which honestly makes no sense as all other apps work just fine.

It all looks like the bug appeared in my iCloud backup after latest update and it seems Apple is not capable of resolving the issue (all in all I was in contact with apple support 5 times during this week)

Would be great to know if you had similar issue and if it was resolved other than restoring the iPhone from the scratch.

Cheers,

Cezary

iPhone 12

Apple Support in the Netherlands listened to me and found multiple reports of the issue, so for sure the issue is recognized now within Apple as related to use of the Calendar with an Exchange account.

The only suggestion was to see if removing my Exchange solved the issue, which I refused as it makes no sense to test with an empty Calendar.

There is no solution yet.

I removed the exchange account and the issue went away. I then added the exchange account back and the issue came back (but not as severe). So it is definitely an issue with an exchange account.

I am experiencing the exact same problem with my calendar. Either it totally freezes, or my schedule at a glance looks completely wrong until I zoom in on the day.

Great! Works for me, but apple really need to address this issue!

Update your OS to iOS 15.2.1. That solved issue with calendar for me.
