Edit button greyed out from payment and shipping’s tab
So I’m trying to buy something in a game on my phone, so I went to the game and clicked the purchase button, and it said I had to verify my card before purchasing. So I clicked continue but it was the wrong card. So I went to Apple Pay and put my new card in and everything, but when I went to purchase the item in the game, it still said the same thing. It turns out that was my default card. So I went to the payments and shipping tab in settings and there was an edit button at the top left, but it’s greyed out and I can’t tap it. Any help?
