My tech team has spent ages developing a Power App specifically because Bookings does not allow the option of recurring appointments. We will be starting to use this in September (and hoping it works!). As an educational institution, we need a bookings app that will allow up to 6 weeks of coaching sessions to be booked by a student or staff member. Not having this feature means that the coach has to manually change an initial booking into a 6-week booking. Since they rarely have the option to do this immediately, other bookings are made which overlap with the six-week service, causing 'double bookings' and a lot of trouble! Hence the time and effort of developing a Power App. This should be an easy thing for MS to implement in their Bookings app.
