Hello, When we cancel or shift a booking, the time slot that had been booked does not become available, even if I add a different employee to the schedule.
I have checked your request locally and was unable to replicate the issue. When changing the date/time of existing booking, the previously booked date/time becomes available for booking. If the issue persists, submit a request to our Help Desk providing more details on the issue and temporary access to your WordPress dashboard.
