I have Business Calendar Pro running on my Android phone. It syncs with NextCloud (snap) Calendar.
Since a week BC Pro does not sync anymore with NC. I get the following errors in the logs:

whatever “Business Calendar Pro” is… if you paid for it, they’ll have support right?

using the default Andoid calendar app or f-droid “fossify calendar” together with recommended DavX5 connected with Nextcloud snap works as intended and recommended by Nextcloud.

It’s actually quite a nice app, but not FOSS. I used to use it, and my girlfriend still uses it. It works well with Nextcloud via DAVx5. Not sure about the built-in CalDAV feature, I never tried setting it up on my girlfriend’s phone, and as far as I know, it didn’t exist yet when I was still using the app.

@secundoego Maybe try deleting the account in the app and setting it up again. See if it throws an error message or provides any kind of debug log. If not, you could also ask here, or use DAVx5 for the actual connection and synchronization with Nextcloud.
