Calendar Event appears multiple times
I encountered an issue where certain calendar events are shown multiple times in my google calendar on android (oneplus3t, oxygenos 4.1.3, android 7.1.1). I host my calendar on my nextcloud (currently v. 11.0.2) and sync it also with thunderbird on pc (45.8.0 on Win10). I've got the suspicion that if I press "remind me later" when an alert for an event pops up in thunderbird that this event will be (displayed?) duplicated by davdroid. Thunderbird still only shows one event as well as the nextcloud webview. But on google calender I get multiple events if I repeat the "remind again" thing. Could that be possible?
Thanks in advance!
