I was struggling a bit with the form, therefore the report is a bit untidy. Is there a way I can edit? If not, should I send a different, cleaned-up version?
Comment 3 Christof Schulze 2025-08-27 13:08:20 UTC
the original vcalender contains multiple vevent entries, all with the same UUID and each of those referencing a different recurrence ID which then has deviating DTSTART and DTEND defined that describe the exception for this recurrence.
It seems, akonadi is not parsing that correctly.
