Hi there!

If Checkbox is off - task marks "complete" in GCal.
Checkbox - "Delete the event that appears on Google Cal but has been marked as "Completed" in Doit.im." doesn't work.

If I add task - sync ok, task appears in GCal.
If I check task complete and\or delete - it doesn't deleting form GCalc.

I did link and unlink GCal for many times per day, nothing helps.
