GCal not working on beta version

You asked me to start new tickets so here we go. Google Calendar is not working since you let me update to the beta version you emailed me. You already have access to my site and know what to look for. We made a new appointment for tomorrow this evening and it is not showing on GCal. An older appointment we set up weeks ago is still there. Also is it safe to update to WP 4.7.2 with the beta version? Thank you.
