The calendar is very slow with latest iOS 15.1 iPhone 6s

The calendar app response is horrible and feels like the screen is frozen, which makes to kill the process and re-launch the app. Didn't have any issues with previous update. Tried re-configuring exchange account multiple times but no luck. Any options to speed up its performance?


Also, are there any fixes to this.

TIA

iPhone 6s

Hello SVEEP,


Thank you for using Apple Support Communities.


We see that your post has not received a response. Perhaps if you could provide more information regarding your issue, someone could provide you with a response. Some information that would be helpful to know:


Where is the calendar hosted? Is it on your iPhone or iCloud?

You mention 'exchange account', is this a Microsoft Exchange calendar?

Any additional information you can provide.


Best regards.

I can reproduce it every time on multiple phones with multiple accounts.

This happens with a Microsoft exchange account's calendar. To reproduce the cal should have many entries on different days.

then just toggle between days and the whole thing is very slow often never refreshing correctly. Does not happen with icloud or google calendar. Only exchange. Have not check hotmail
