calendar is slow to respond after update to ios 15.1 on iphone XSmax

Yes! Me too!

That is exactly what I am dealing with

same issue here on iPad Pro 2020 model after latest software upgrade... fortunately not on iphone (XR)... mostly use ipad for total view of all calendars and this is really annoying

I cannot blame you, this is really a bad issue and Apple is not providing an official answer nor a remediation path for a final solution.

I reset set all settings and no help with the sluggishness. It’s painfully slow abs then freezes. iPhone 13 max here.

I have an iPhone 11 with the same problem. It occurs to me that even the newest MacOSX has this problem but in a little minor way.

It has been posted just one day before this one.

A fix and much improved performance is on their way for both iOS and for macOS!

Thanks for flagging! Updating now!

I have same issue on my work iphone SE after 15.1 update. My calendar is so slow and won't respond to touch.

OK. Noted. Thank you

Thank you for the workaround.

Switching off wifi seems to work on my devices.
