I'm using KDE 4.13 with Korganizer, not Kontact complete suite. When I add the 'Google Calendar Resource' as calendar, all items of Google calendar are imported fine.
But additional entries in KDE or in Website Google calendar are NOT synchronized with each other
Steps to Reproduce:
1. Install Korganizer
2.Add a Google calendar resource with your own gmail address
3.Enter additional events, either in Korganizer or in Google Web calendar.
Calendars are not synchronized
You can NOT refresh with 'F5' key, the menue entry is grey, not black as known from KDE 4.8.
Expect to refresh (actualise) automatically after few minutes.
This was given in KDE 4.8 and up.
Essential feature for me.
Very late sync (not sure) or no sync at all.
