Appointments Gcal sync issue

Has Google calendar (Online Calendar) configured under Appointments > Settings > Google Calendar, and have configured Google Calendar for each service provider.

When checking Gcal for each service provider calendars, it gets booked correctly for each in Googles calendar side without any issue.

But, when it’s checked in the appointments page, under /online-appointments. The page is only showing that the booking is getting reflected to the “Online Calendar” under, /online-appointment

The time slots isn’t showing free/busy when checked for different service providers in the /online-appointments page.
