After I got my iPhone 6, there weren't many places that took Apple Pay...i tried it at Subway and it worked there at first and then it worked at Walgreens too. I mostly used AmEx cards and Citibank cards. However, once my bank finally started being Apple Pay capable (TCF Bank) it hasn't worked as well. Whether or not that has anything to do with it i don't know, but now it almost never works at Subway and it rarely works at Walgreens. Any suggestions or should I bring my iPhone 6 to Apple and get it switched out?
