I think teachers should decide if they want to offer recurring lessons or not. Personally, I can't guarantee any student that I will be available on a specific date next month because I don't know yet what I might be doing that day. Furthermore, I've seen that in other teaching platforms with this option automatic booking becomes a problem. When a student books several lessons in advance it is more likely that he wouldn't be able to attend them all, or even forgets about that lesson scheduled one month ago. I've seen cases where a student activates some kind of automatic booking, and he doesn't even knows how to deactivate it. It also might promote booking lessons which will be cancelled later. Therefore, the teacher spends time with a spot booked, and lessons can be cancelled just a couple of days earlier, when it's complicated to find another student in order to fill that spot.
