No way to change duration – ParkMobile: Park. Pay. Go. Review

I spent 15 minutes trying to figure out how to change the parking duration from the max time. Ended up paying $20 for a 13.5 hours when all I needed was maybe 3 hours. Would have looked for a side street spot but the event was about to start and I didn’t have time.
