It sent me through a busy business/strip mall in Tuscon only to send me to a NO LEFT TURN intersection to turn left at. Going past the intersection left me no opportunities to U-Turn and to smaller and smaller roads.

Almost certainly the app was set for the shortest route, always use fastest time.

Never, ever, never use a shortest route setting, that overrides any restrictions in every brand GPS and every app I've seen including Co-Pilot.
