I just updated to iOS 15.1 and the calendar has lag issues. When first opened it shows the wrong events on the wrong days and wrong times. Also events are displayed with overlapping text. If I switch between apps it corrects itself.
iPhone 11
Hey there Binkobinko,
Thanks for reaching out to Apple Support Communities. Based on the info you provided, start with just restarting your iPhone and see if that helps:
If that doesn’t help, delete Calendar, restart your iPhone, then reinstall and see if the issue is resolved.
Take care.
Restarting fixed the calendar
Issue is happening on my side also. Here’s more details. IPhone X ios 15.1
if you’re viewing the entire month at once with the daily events at the bottom of the screen, changing day is going to create a freeze/lag and scrolling through the events at the bottom is laggy.
same is happening if you go on the event only view.
a lots of people are on this thread below. Seems like Apple is aware of this

The problem is back again. I deleted the calendar app and re added. Still broken.
After restarting my phone and deleting the calendar I thought the problem was fixed. I’m seeing wrong events on the wrong days.
