`Add New Card` page not working in staging version

I was trying to test integration of the transak onramp into my dapp at staging environment.

But after the short KYC, select the fiat & Cryptocurrency, destination wallet, etc... I can't add a new card.

The page going round and round in circles, and I can't go to next steps.

Can you please identify the issues and provide the solution?

Best
