Hi guys, I have recently replaced the rear housing on my iPhone 8. Basically took out all parts from the old one and put it into the new one. When I put it all together, the wireless charging did not work (did not check Apple Pay at that time). I thought I might’ve damaged the sticker antenna, so bought a new one and installed it. Now the charging works, but Apple pay does not. Does Apple pay & Wireless charging use the same antenna? Any ides of what I should be looking at to fix this ? Thanks!

The answer in this thread helped - After replacing housing apple pay not working it was the metal bit that goes around the rear camera. Tightened the screws and apple pay works!
