Appointments not syncing when editing appointment information or time

My appointments have not been syncing to my google calendar upon update of time or information. Please help.

If I adjust the style a client wants, the appointment does not adjust on my google calendar, if I change the date on the appointment it does not update on my google calendar, if I change the time of the appointment it does not change on my google calendar. This has been happening for a long time, I just can't take it anymore which is why I am asking support to address this issue.

Thanks!
