Hello Marcelo11756,
I am sorry to hear that your google calendar stop syncing. I want to let you know that we are aware of this issue, where automatic sync is not working which is causing your google calendar not to sync. Our team is actively working on it to resolve the issue asap. In the meantime, you can still sync your calendar through manual sync.
Herewith attaching a screenshot to explain how you can still sync Manually.
Log in to your method account and then click on the Upper right corner of the screen on your Username and then click on My Profile, after that click on Google calendar and then you will see in the right side pane Sync Now option to sync it manually.
I hope this helps.
