Ifixit has a note/disclaimer that states replacing the screen disables the NFC antenna. Mine will not load wallet onto watch as well. Looking at a video where they pried off the old NFC assembly and reinstalled it on the new screen to fix this issue. I think this is what Ifixit means by “no easy fix”….but is fixable but would void new screen warranty. Haven’t tried it, as this issue was not a deal breaker for me.
