I work from different offices on different days of the week. So have configured Service providers, and services based on:
CBD Office - Monday and Tuesday
Parnell Office - Wednesday
Takapuna Office - Thursday and Friday
Have created dummy providers, assegined them to the respective locations, and have Gcal integration configured in the Appointments >Settings > Gcal tab.
The current issue, is when trying to manually create an event in Gcal, and it doesn't get synced in the plugin, and mark the days as busy in the /make-an-appointment page.
Please check the chat transcript for more info.
