Booked User Emails not sent

Hello,

So, I’m having problem with email notifications.

Right now, when a visitor creates an event, admin receives notification about new event, but the user who created the event doesn’t receive notification.

Mail sending method is set to SMTP, and when I try “Test email settings” button, I do receive test email. Also, like I said, admin is receiving notifications without any problem. Only problem is with visitor who created the event.

Can you please help
