@wesselah I experienced the same behaviour for many weeks, but as of 2025.12 it seems to be fixed, i.e. I've never seen the unavailable status anymore since this upgrade.

How about you? I didn't see any version bump for the CalDav integration in the latest release notes, but I might have missed it.
