We have been using the classic app because the new app is just so unusable. This morning our quick fill list had vanished on the classic app and we are unable to add new people to it. They are all there on the new app. So we tried to send out openings on the new app. You can't send more than one appointment time! This will cause so much extra work for us and we don't have time for this. Also, when you add people to the quick fill on the new app is forces you to choose "location." We only have one location and there is no way to change this. It is unusable. This needs to also be changed. We want to continue with the classic app. Please fix this.
