I have just scoured the threads and google for a solution to this problem and am coming up empty.
All of my appointments in the system are off by 1 hour. All of my users book directly through the system or admin adds appointments in. Nothing is being done via GCal.
This is a major flaw / breaking point for the Appointments+ plugin and needs to be addressed with a solution prior to the next shift in November.
How can I fix this?
