I got a new Watch 4 LTE from TMobile and I did get Google Pay set up on it, and it works, with limitations. It appears that when I tip my wrist back to place the watch near the reader, the screen shuts off and apparently, this may be preventing the NFC from working. If I contort myself the opposite direction so the screen doesn't shut off, Google pay works fine, but it's uncomfortable and just looks weird. As for Samsung Pay, I had it set up on my old watch and I told it I would be moving it to the new watch. This apparently requires an update of the watch app on the Watch 4, which consistently fails. I had a similar issue on my old watch and turning off WiFi on my phone seemed to fix it, but that's not the case here. Anyone have ideas? Can I sideload the Samsung Pay watch app through wireless ADB?
