Editing / Deleting one occurrence of a recurring calendar event → 2nd invitation IMIT mail is very confusing

[kusmi]

### Steps to reproduce 1. Set a new recurring calendar event (e.g. starting from June 1, 10:00, every week) 2. Add an external attendee and click save 3. Normal invitation email is sent out → all ok 4. Reschedule a single occurrence (e.g. move the June 22, 10:00 event to 15:00) and save 5. Another email notification is sent out, but the text is very confusing: "You have been invited to ... June 1, 10:00) - so the old date is still displayed in email, no mention of the rescheduling of the June 22 event. ### Expected behaviour Second notification email should state, that the June 22 event has been rescheduled. ### Actual behaviour Second notification email does not display the rescheduled date/time. Instead the same email is sent out as in original notification email (just without accept button) ### Calendar app **Calendar app version:** 2.0.3 **CalDAV-clients used:** It happens with Nextcloud webversion, as well if I reschedule on CalDAV-clients (e.g. macOS Calendar app) ### Client configuration **Browser:** Safari 13.1.1 (15609.2.9.1.2) **Operating system:** macOS 10.15.5 (19F101) ### Server configuration **Operating system**: Hetzner NextCloud **Web server:** Hetzner NextCloud **Database:** mysql 10.3.23 **PHP version:** 7.3.17 **Nextcloud Version:** 18.0.4 **Updated from an older installed version or fresh install:** Updated from 17 - but long time ago

An attempt to fix this was done in https://github.com/nextcloud/server/pull/13892 already. It improved the situation a bit, but still fails partly as:

• It would always show the next occurrence (✅ if all future occurrences are modified, ❌ when only some future occurrences are modified)
• It should should the one modified occurrence that when only one was changed instead of all future occurrences after X
