I have had some sync issue with my google calendars and my iphone / ipad / macOs calendar app so I have decided to try to fix it. I removed / add Google Account from my iphone and now I can see the calendar without issue. The problem is with Calendar desktop application (on MacOS).
I followed all the instructions but, what I can see not on iCal is the Account Google but no calendars (check the picture).
Any clue? I followed all the instructions I have found on google support pages but without success.
