Rated 3 out of 5 stars

Just uninstal version 1.0.1 and re install previous version here:https://addons.mozilla.org/fr/thunderbird/addon/4631/versions/
and let's give time for a corrected 1.01(2) version... and do safety copies of google calendar. This issue crashed 50% of my calendar... my fault, I made no safety. And uncross automatic updates!!! Conceptors are not gods, and google can change whatever without telling anyone....

This review is for a previous version of the add-on (1.0.1).
