Why change the behavior without notifying?
It's unfortunate that everytime Amazon changes this app, it seems to go the wrong way. I now have a very slow app, and for some reason the balance reload changed to pick my default buying card. It used to work great by using a different default card. I have a credit card to pay for purchases and a debit card for reloads. The app knew this before, now they decided it was not good enough and I have to remember what card to use for what purpose. Seriously, no UX experts running that show.
