Accepting an invitation from an email does not add the event to the calendar

Accepting an invitation from an email does not add the event to the calendar (any of the calendars).

Email:

Clicking on "Accept":

When I open the Nextcloud calendar app (web UI) though, there is no event entry for the date that I just accepted. I would expect that there would be an event in my calendar.

I can only add the event to my calendar when I import the .ics attachment in the email via my email client (in my case Evolution). But I would expect that the "Accept" button that leads to the NC web UI does exactly that for me.

Additionally: if you have more than one calendar, the user should get asked which calendar to add it to.

Not sure if this is now more of a bug or an enhancement. Happening on the current calendar app version on cloud.nextcloud.com

GitMate.io thinks possibly related issues are #3464 (Thunderbird/Lightning: Event invitations cannot be added to a nextcloud CalDAV calendar), #2338 (Accept calendar invitation directly in the invitation email ), #3830 (No calendar invitation send for event in shared calendars ), #2855 (Invitation send to attendees upon calendar import (also for past events)), and #3014 (Calendar event invitation automatically creates a new 'personal' calendar).

+1 same issue here on NC15, accepting on K9 takes me to the nextcloud page telling event has been added but it's not.
importing the .ics file into business agenda (Android) is fastidious and said to contain "errors", in the end it is still not added.
Clicking on accpet in Thunderbird (Windows) presents the same bug.
