When no times are shown
When no times are shown in the booking widget, this can have multiple reasons:
1. At the appointment type it is chosen that bookings can be made up to a specific time in the future, but the entered availability lays after this date. To modify this, you go to Manage > Services and choose 'Edit' at the relevant appointment type (note pad with pen). Here you can change the period at 'Maximum time before appointment'.
2. The duration of the appointment type including the buffer time is greater than the created block availability.
