I successfully linked my Square with Google Calendar, and synced - customers can book online via Google page. I am not able to change Google Cancellation policy that is 90 days! How to change this number from 90 days to 1 day or less (1 hour)?
Google has their own rules. I have not found a way to update it either.
Also, if you are utilizing the no-show protection through Square, this DOES NOT carry over on Google. About 30% of my Google bookings were no shows so I had to turn off the sync and just use the link.
