Samsung Pay on Gear S3 UK TFL card

[Danred1]

I finally received Samsung Pay on my Gear S3 today but it doesn't seem to work on the tube to tap in. Is anyone else having the same problem? I tried tapping without opening the app to see if it would work like the phone as a travel card and then tried activating it as if paying in a shop. Neither worked. It's been working flawlessly in shops all day.
