Apple Wallet says card invalid

I had a card in my Apple Wallet from NetSpend Skylight One with no problems. I was contacted by the card issuer to upgrade my account with a new card that is issued by Republic Bank & Trust. I checked and this bank IS accepted by Apple Pay. However, it will not allow me to add it. I continue to try to add it and it says my card is invalid. I also contacted my card issuer and I was told that permission is in place for Apple Pay to accept the card and to contact your end. I’ve never ran into this issue and since I use Apple Pay ALL the time I’m getting frustrated and very, very concerned that it is not being accepted. Also, my iPhone has the most recently updated IOS version.
