I recently had the misfortune to shatter the glass screen on my watch - it split away from the case (and the glass was cracked.) Apple deemed it non-repairable. I didn't have apple care, but did have insurance (Barclays UK gadget insurance) and lifestyle insurance group did repair it (it's not a replacement) The repair looks good, it all seems to work fine. Except for one thing. For the life of me I cannot get Apple Pay to work. I used this extensively prior to the repair, and I use it on phone too. My watch is at 3.2.3 (non beta) and phone is at IOS 11 - latest public beta (I still want to compare/check the screen against another series 2/42mm to ensure I have the 1000 nit screen. another one it's a bit tough to check though so far seems bright outdoors) I've tried - restoring from backup (about 3 times) - a clean install (twice) - adding a card during setup - adding a card later - trying to add an existing card the phone sees, or a new one but whatever I try I get Could not Set Up Apple Pay An error occurred while setting up Apple Pay OK Is there anything about a replacement screen that could break Apple Pay. I know with iPhone there is a touchid pairing issue, but not sure if there's anything with NFC. I guess the component could be faulty/disconnected but any tips on how to check Potentially I may try capturing some system logs as I just switched my work laptop to macOS this week and have been experimenting with Xcode (nothing on watch!) My gut feel is the repair is bad in some way, but I'm trying to figure out how to demonstrate that. It's also possible it's a setup issue relating to iOS 11, so I may try and do the setup with a friend on iOS 10 to double check Thanks Nigel.
