My World Cards Dont Work - Useless

I have two different domestic MasterCards -- a World and a World Elite. Neither of them are recognized by the apps. Unless you can get the cards to work, this is app is totally worthless.

Its a shame because MC has some nice benefits, but they are not easily accessible.

Please fix this glitch so all MC World and World Elite cards can access this app.
