Hi,
Had a xr with badly cracked glass on the back. I got new housing and have replaced it. I used all the original parts from the xr, following guides on ifixit and keeping all screws etc in place . Everything works like it should including wireless charging but apple pay wont work. It comes up to pay but wont talk to the card reader. No error msg comes up , it's just like the card reader ain't there. Have I missed so.ethjng when swapping the housing . Thanks
