I recently upgraded to Nextcloud 18.0.3, which upgraded my calendar to 2.0.3. When I went into the server settings and went into Groupware, I saw a setting I think I had never seen before:
Enable notifications for events via push
I turned this feature on, and my wife entered an event in our shared calendar, and the Nextcloud app on my iPhone got a push notification.
The problem I am facing is that I am unable to duplicate these results. I added a few more events to the shared calendar, and no notifications were pushed to my iPhone or my iPad.
What am I doing wrong here?
