Can't accept a recursive event from the calendar web UI

[section1]

Steps to reproduce

1. UserA creates a recursive event like all Saturdays at 13hs and put UserB as guest
2. UserB sees in the nextcloud calendar the event and the recurrent event fine
3. UserB can't 'Accept All' . you have only a "Accept" button and if you click there only accept that occurrence of the serie.

Expected behavior

UserB have an Accept All button for recursive events and when click this button accepts the recurrent event/complete serie.

Actual behaviour

UserB have to accept occurrence by occurrence in the serie.

Is the event you're trying to accept the recurrence from the first in the series or one in the middle?

Hi @miaulalala I re-test this again in a NC 27.7.11 and Calendar app 4.7.14 and opening the First event of the serie still can't accept the whole serie.. If i'm not wrong I recall to see a button that says "Accept All" in the past(maybe i'm wrong).
