This message means that one of your connected calendars is not syncing correctly.

To fix this, get to your dashboard, click on your profile on the top right, then "calendars" and refresh the list.

If it doesn't solve it, try this:

Once this is done you need to reset Koalendar access to your Google Calendar. To do so, go on this page, find Koalendar in the "Third-party apps" list, and click on "Remove access"

Then log out and lock back in on

If you still get the error after going through those steps, please contact us directly on the chatbox or by email.
