Since december I don’t get any confirmationmails when somebody planning an appointment via YCBM account. I don’t know how to fix this. I don’t get any of the e-mails. Also not when somebody reschedules the appointment.
@Harm it looks like your account email was unsubscribed from getting notifications from us. I have re-subscribed it. I also see that you have used a @hotmail address to get the booking confirmation. You may want to check the Spam folder there for confirmations.
I can see some emails being delivered. If you are sending the email to and from the same address, it may not go through. Can you test using a different email for your booker?
