Hi @james- I have a client who booked a class twice, while it set as “can be booked 1 times by a single person”. So this shouldn’t be possible. Could you look into this please? Thanks! Virginie
Nice to hear from you, I’m sorry for the delay in replying to this.
Well this is strange: I had a quick look at your setup and everything looks correct. Could you possibly send the email address of the student to [email protected] and I’ll investigate what happened? Also please let me know asap if this happens again.
I hope you’re doing well. The email is: 
I am sorry @Virginie_F - I can see this student but their appointment history looks ok to me. I’m guessing this is because you deleted the duplicate appointment? I really hate to be a pain but could you send the date / time of the appointment to [email protected] ? There’s a fair amount of background information + history for each appointment so with that I can investigate further.
