Apple Pay not working after rear glass replacement/wireless coil

Hi,

I have a 13 Pro Max that I have replaced the back glass via laser method.

Rear flash would not work after this, So I replaced flash flex and GPS flex as it looked damaged as well. Both of these work perfectly now but Apple Pay would not work.

I have now replaced the wireless coil w/ volume and power buttons. Again all these features work perfectly still but alas no Apple Pay.

Any ideas? Thanks
