Fixed in production - give it a go.
Nextcloud calendar write permissions doesn't update in DAVdroid
I’ve used DAVdroid for a while in combination with my own Nextcloud server. Works perfectly fine: I have an overview of my own and shared calendars on my phone and sync as expected.
I just changed in Nextcloud the permissions of a shared calendar, so that I can now also edit that shared calendar. It works in the Nextcloud web-interface. However, when I sync in DAVdroid, or Etar (my calendar app), then the permissions don’t get updated. In other words, in DAVdroid I still get the icon.
Instead I suspected that I now should get write access to that calendar (I guess removing & again installing the account works, but just wanted to check first).
DAVdroid debug info
Right beside the CardDAV section in your DAVdroid account is a little option bar. Click it and refresh your collections to update the settings of it. After it the “read only” flag should be removed.
Hope it helps
Oh, thanks. That worked. I assumed the general sync would work as well.
