OS: macOS Ventura App: Apple Calendar
With the most recent Ventura version (and Apple Calendar) we are experiencing an issue with events that are initially added to the user's calendar (containing a predefined UID) and since then updated with the same UID.
On the second event add/update, the event is not updated.
Once the initial event has been added to Apple Calendar, we exported the calendar feed and noticed that the specific event had gotten an additional UID applied to the .ics file which we suspect is the cause of the issue.
Steps:
- Download this .ics file and add it to Apple Calendar
https://phpphp.dk/apple1.ics
This .ics file contains an initial headline. The SEQUENCE field is set to "0" and the UID is predefined to "hellouid".
- Download this .ics file and add it to Apple Calendar:
https://phpphp.dk/apple2.ics
This .ics file contains a different headline. The SEQUENCE field is set to "1" and the UID is set to "hellouid".
Expected behavior:
- The event details should update to the newest version in Apple Calendar.
Actual behavior:
- The event is focused on Apple Calendar and the event details are not updated.
