Unable to set appt time range because of app design – FollowMyHealth® Review

There’s a slider to let your provider know which timeframe to schedule your appointment in but the left side cant be slid because dragging from left edge toward right takes you to the previous screen instead. Only the right side of the time range can be moved and that doesn't help me since I was trying to say no appointments in the morning.
