Cannot pay on vendor machines withApple wallet

Fellow community, I need help with Apple Wallet. Right now, I cannot pay for any services online as double-tapping is not working. Also, it does not allow me to pay at vending machines, while doble-tapping home button on the side, it just unlocks my phone. This is iPhone XR.

is it shown as pending transaction? if yes then it might authorization hold issue
