Lately I've been having many problems with Appointment plus.
The latest one is that it is showing time slots as not possible to book when there is nothing booked in that spot. Gym usage appointments are solo training without a trainer and it seems that the program is saying it's not possible to use the gym when I am booked. This shouldn't be the case. It should be set up that two other people can use the gym at the same time as I am training someone. I enabled suppport so you can look and if need be modify any errors. It has become very troublesome.
Hope someone has a solution.
