I too was affected by Google disabling v1 of Provider::GData API for Calendar yesterday. Did you submit the Postbox version of your plugin as well, as per the link below?

If you did, do you plan to update the Postbox version to use a newer version of the API? Please reply here if you have a minute. Thank you for your hard work on this calendar integration.

This review is for a previous version of the add-on (1.0.2).
