I never enabled sending follow-up emails after appointments, but I discovered that you are now emailing people to invite them to book another appointment. I bought Tidycal to use it for scheduling interviews, and now candidates I have rejected are being invited to schedule new interviews or submit reviews. WTF!!! There should a system-wide option to enable/disable post-appointment automated communications, not a setting I have to manually disable in every booking type! (And it should default to being disabled!)
