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 / added my 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 while I can see Google listed on iCal, I can't see my Google calendars (check the picture).
I've tried all the instructions on Google's support pages but without success.
What else can I do to fix this issue?
