Apple Watch Paywave Didnt Work!

After a moment, i tried to paywave using apple watch. It didnt work! I tried using phones, turns out just fine. For months ive been thinking why?? Maybe i went to a diving then the wave got problem. Then i ask my mutuals, they said maybe because i didnt update the watchos to latest version. Until i search up again and found someone mentioned it has something to do with assistive touch. I remember i turned on the assistive touch just to show off to my sister how i can control the **** watch using gestures.

go to accessibility - assistive touch - on - off the confirm with assistive touch - off again. Then "hold near reader" will appear again in wallet.
