I have trouble setting a home address, and alternating already saved addresses. When I try to schedule an appointment it’s confusing going through the steps. Also I’m concerned when I go to schedule a pickup for a doctors appointment that I will be there on time. For example I had an appointment at 9am, I entered that I would need a pickup at 8am to allow for 45 min of travel; the app told me I would arrive after 10:30am.
