If all else fails I'm wondering if removing them and then re scanning them / entering them may help ?
Failing that have a look on your region's Samsung Support page in regards to cards not activating via Samsung Pay.
Personally I use Google Pay and have had no issues when changing phones.
If I can be of any further help then please don't hesitate. Take care. 😎

The advice I offer is my own and does not represent Samsung’s position.
