I have used the following short codes:
[app_services select="Please select type of session" description="excerpt"]
[app_pagination ... month="1"]
[app_confirmation title="Please check the appointment details below and confirm:" button_text="Please click here to confirm this appointment" confirm_text="We have received your appointment. Thanks!"]
... the problem is that when making the booking the confirmation text is not shown (We have received your appointment. Thanks!
Note, I am not using Paypal on the site, when people make the booking online all I do is to confirm it in the system.
Also, I still do not receive any email notification from Appointments+ when bookings are made, nor do the customers receive anything.
