Problem with Google Calendar connection and synchronization

Hi.

During the first testing, I was still able to connect the plugin to Google Calendar. However, 2-way synchronization was not achieved.

Now I put it for the second time for testing, and the plugin basically does not connect to the Google Calendar, although all permissions are given to it.

In general, I don”t yet see the work of the important declared functions.

Sincerely,
Farid Taziev.
