Calendar sync working one-direction


I was trying to set up new calendar account (after being locked out of using my Gcal account by Alphabet’s stupid privacy update). I decided for a Nextcloud/OpsOne/DAVx5 combo.

However, the event sync only works one-direction (not to be confused with the band One Direction). Events that I create manually in the web interface get downloaded and shown in my calendar app but those imported from Gcal online via an .ics file do not appear in the OpsOne web interface. Not really a sync I was hoping for when it’s not syncing. Any suggestions?
