I'm trying to add my Revolut or N26 card to Samsung pay on my watch and I'm getting the following message: Card issuer not supported, this card issuer is not supported by Samsung pay, try other cards.
I am not sure what is happening, but same here, can't add revolut on my galaxy watch 4, my note 10+ 5G nfc stopped working and can't add revolut card to it
This is not Samsung's fault and is instead up to Revolut and N26 to build their products to support Samsung Pay. They are however limited to only Google and Apple Pay.
