Update needed
iOS 15 Crash - Calendar Bug
Clunky app with poor interface
Another issue with bookings: sometimes when I cancel wait list, instead of being deleted, it converts to a full booking.
Booking multiple sessions is a time consuming process. Why do I have to go back several steps to book another session? Why not create a calendar view and show booked sessions in that view, rather than in a separate list that is very hard to make sense of unless you have a calendar in front of you to overlay it with?
You may want to learn from F45. Used them before, and the app was far superior to this one.
