When an end user is going through the booking process and your account is configured to accept online payments, after the payment has been accepted the appointment will not finalize and the individual booking the appointment will be presented with an error message stating the appointment does not fit in the selected time slot.
Temporary work around
To resolve this issue and allow your end users to successfully schedule their appointments you can make a slight adjustment to your account configuration.
This can be done by going to:
Settings > Customer View Preferences (Term "Customer" may have been changed in your account) > Set preference #32 to No > Update.
