Where did the map go??

After recent update, it’s much harder to find a locker… There’s no longer a map. It’s just so horrible to use

Latest update is a big backward step.

This app used to be really responsive and useful for opening my locker with a single tap. Now it takes a good 10 seconds to open and get ready for me to open my locker. And then I have to dismiss a prompt before my locker is open.

It’s now mostly useless for my use case. It’s now quicker to walkover to the card reader to open my locker and walk back.
