The ease to schedule or cancel classes through my phone has greatly improved our school's productivity during this time where we are all working remotely due in part COVID 19 restrictions/pandemic issues have been ongoing now since March 2020 (at least).
This was not an issue prior before but there seems like more people cancelling scheduled sessions than actually showing up which I find odd because it would mean they were just wasting money paying them as well so maybe some better communication needs at times? Not sure though honestly haven't had any problems myself yet only trying out new features here & seeing how easy things work overall compared when doing class schedules back then via paper calendars etc..
