I have contacted Google pay & the told me same thing already have done! Set up on my Samsung Smart watch classic4! Set up fine then got up date & had to reinstall Google Pay! Have CC verified & in app on watch, set nfc default to Google Pay & will not work on my watch! But works from my phone! Talked to T-mobile & they did everything they could! Talked to GOOGLE tech they submitted trouble ticket & they emailed! Said reboot, factory reset & reinstall! Phone state update 1/10 & watch 2/6🤬
