Calendar sync doesn't work
Since version 0.8.3 (or 0.8.2) the calendar sync with Kolabnow.com doesn’t work at all.
Just tested it, everything works fine here. Ususally we test kolabnow very well, we’ve not received any reports yet, too. Do you have steps to reproduce? What exactly is not working?
The app crashes while syncing the calendar.
