If you have a full class, but a regular client turns up that you are happy to train, you can quickly and easily do this, provided you have 'Allow staff to increase class capacity' enabled.
To enable this setting, go to Settings, select the 'Booking' tab and enable 'Allow staff to increase class capacity'. Ensure to save your changes!
When enabled, you and your team (Trainers, Receptionists and Admins) will be able to book a client into a class which is already fully booked from your Dashboard or from Glofox Pro.
You will get a notification ensuring you know that this will increase the class's capacity before successfully adding the client to the booked list.
