iPhone Calendar: Repeated 'Location changed' notices
Repeated address change notifications in Calendar after adding a stay from Booking.com
iPhone 16 Pro, iOS 26.5
How to repro:
Book something in Booking.com in advance (give yourself a few days)
Add a booking from Booking.com to your calendar
Notice that about once per day, you get a calendar notification for the booking that "Location changed" - except it hasn't.
Accept the location change to make it go away. (I can find the notice after accepting)
Reported here and closed with no actual help so now I have to spend my time re-reporting it instead of just giving a comment: Repeated Address Change Notifications fro… - Apple Community
