Another music school owner here, wishing for the same feature. I can’t use Wix for my bookings because of this–with 100 students and 3 teachers, it is just way too much work to enter every single lesson, every single week! And I can’t expect my students to enter every single one of their appointments either. It seems like recurring appointments should be an essential part of a bookings platform. Please add this feature, Wix!
As for workarounds, I’m afraid I don’t have a magic bullet. I use a combination of my own homemade database, Google calendar, and lots and lots of emails to students confirming their lesson dates and times!
