Can’t Verify Credit Card, Required Fields Error

[jkleeedo]

I’m trying to verify my credit card to unlock the custom domain options, but every time I attempt to do so, I receive the message: “Please fill in all required fields.” All fields are already filled in. I’ve searched for solutions, but none have worked so far. I’ve also tried using different browsers (Brave, Chrome, Chromium and Firefox), incognito mode, and my smartphone, but the issue persists.
