My driver's license is in a form factor Apple cannot scan. A few months ago, I tried to get it scanned four times (with the UI telling me various versions of "your ID is too blurry" / "there was a technical issue") before Apple just blocked me from applying for the developer program.

Their support gave me the exact same template: "After reviewing your account details, it looks like we can’t verify your identity with the Apple Developer app or provide further assistance with the Apple Account for Apple developer programs."

I was only unblocked recently (surprisingly -- I thought I was banned forever), and so I decided to try applying with passport instead. That got further, as instead of saying my ID image was blurry, it said "ID Verification Rejected".

I am in contact with developer support right now and they told me that one of my devices or phone numbers was registered with another developer account, but they haven't told me which one (only to "remove phone numbers and devices that you don’t own" -- which isn't applicable as I own all of them).

They're taking 4+ days to reply each time though, which is super frustrating.
