Does Apple Pay Cash Instant Transfer support Mastercard Debit cards?

Hi,

I have a balance on my Apple Pay Cash. I'm trying to transfer funds to my bank account using Instant Transfer via the debit card option (since the bank account method takes 1-3 days). I have a Suntrust Mastercard debit card. This card has already been added to my wallet.

However, when I select that option, I receive a prompt with two additional options:

1. Add debit card
2. Add debit card later

If I select option 2, it takes me back to the main screen.

If I select option 1, a screen pops up to add my debit card. I proceed to add my Mastercard debit card details, only to receive the message "This card is already in your wallet."

I have tried deleting my Mastercard debit card and re-adding it when that prompt pops up, only to be taken back to the main screen and repeat the above cycle.

I've searched Apple communities and other resources online. There is no mention of whether Apple Pay Cash instant transfer supports Mastercard debit cards one way or another.

Can we get an answer on this?
