I don't know which forum would be right for this, since there isn't a forum I could find for the S3, so I guess I'll post it here. I just got a Gear S3 AT&T LTE Version, setup numbersync, and went to go setup Samsung Pay. However, any time I attempt to add a card, it says "registration failed" and tells me it failed to register the card and try again later. It does this with every single card I try and enter. I have attempted unstinting the App, and reinstalling but no avail. It works fine on my S7 Edge, with the same cards, but not on the gear. Any ideas?
