Latest update has now made it impossible to retrieve orders from the same hub lockers I had no issue with before. When I click "Start Pickup", it thinks for a second but then crashes and brings me back to the main page of the app. After spending over an hour on the phone with Amazon Support, they advised me that they'll be investigating so they'll be investigating and that I'd receive an email in a few hours with an update. After 2 days, I never heard anything so I ended up getting a refund.
