This is genuinely so frustrating and unfair. Booking rarely works for me on the app, and I am completely unable to cancel classes through the app on my Google Pixel. I have stopped going to classes because my options are sign up with no option to cancel, and be charged unfairly (I try to call the front desk and they only pick up about half the time), or go to class without a booking and be humiliated by the person walking around checking for sign ups. I will likely cancel my membership because of this inexcusable issue.
