Apple Pay - Card Device Limit
So here's a weird one.
I have been trying to add my credit card back into Apple Pay after doing some restores etc. Previously it just said that the card couldn't be added, but didn't give a reason. Now, it appears that there is a "Card Device Limit" (see the screenshot). I searched like crazy, but didn't find anyone else who had/has this issue.
I am assuming the card registration process somehow ties the card to the device or software installation, but I don't see where to remove them.
