Google Fi doesn't accept Revolut card

Today I tried to add my Revolut card as a payment method to Google Fi mobile service fi.google.com. But it didn’t accept as “it was unable to complete the transaction; prepaid cards can’t be used”.
It is frustrating that Revolut continues to use prepaid card in the US. They should change their cards to true debit cards so that it can be used where a debit is required to complete the transactions.

i have set up my Revolut card in my google account and never had issues with payments. Even with Google Fi, every month the bill is paid via Revolut.
