I am also having the same problem. We have All Attendees selected on the reminder emails however the only people that receive the reminder emails are the assigned staff.
I created a test appointment using my personal email as the client. I received the appointment confirmation but did not receive the reminder emails. I also tested as the "client" accepting the appointment and adding to my calendar and still did not receive the reminder email.
Were you able to get any additional information on how to update bookings or whether this is a bug? Thank you.
