Stopped working Rated 3 out of 5 stars

This was excellent for sync'ing calendars with my Android but has stopped working properly a couple of weeks ago. I get a frequent dialog (as per sync frequency, i guess) that says "An error occurred when writing to the calendar Work!" and "Error code: MODIFICATION_FAILED". I once solved the problem by deleting the calendar and re-defining it. Now the problem ahs recurred. I am unable to find a reason through Google - no record of recent changes that could have caused this.

This review is for a previous version of the add-on (0.18).
