Rated 2 out of 5 stars

Necessary but it is a pain to have to log in every time I open my windows desktop computer.. especially as it takes three distinct steps and the accept button is not visible and the window not resizable. Tab key works most of the time but not always.. plus I get two emails on my phone and computer to tell me I have logged.. I know that.. and it has been a pain doing it! And I have enabled cookies but not improvement.

This review is for a previous version of the add-on (3.1). 

Could you try unsubscribing from all Google Calendars and then setting them up again? Normally it should work without issues. Please note that re-subscribing may take a while with large calendars since a full sync needs to happen on the first refresh.
