could not set up Apple Pay - an error occurred while setting up apple pay
I am trying to set up Apple Pay on my new MacBook Pro. In Settings, I click on Wallet & Apple Pay, then Add a Card, and then the above message is displayed. I have checked that Language and Region are correct, set it to another region, then set it back to the US, and tried signing in and out of my Apple ID.
There are no other suitable options given in the solutions to this problem on the relevant Apple support page.
Also, possibly related, under Touch ID in Settings, I am not able to select Apple Pay or iTunes for use with Touch ID.
Yesterday I updated to Big Sur, perhaps this could be the problem?
