Neither for me. Keep finger crossed for the rest of the day
The JSON file has not been updated yet and it is said that this is the last step apples does, to show the 'add card' function in the wallet app. (I have a script checking for that JSON file every 30 minutes)
before apple changes that JSON file all the banks will have activated their APIs. so you will be able to add ur card using another region setting (to show the 'add card' function)
so at the moment, the only way to check if something has been changes is changing the region settings and trying to add a card issued by a supporting bank
