Hello Apple Developer Support,
For two months, the enrollment page at developer.apple.com/programs/enroll shows this message: "We are unable to process your request. An unknown error occurred."
The error appears in Safari on Mac after I choose "Individual / Sole Proprietor" and click Continue. App Store Connect (appstoreconnect.apple.com) shows the same "Unknown error." Signing in to the Apple Developer app on my iPhone works well with the same Apple ID.
I have written to support earlier and still await a reply. Please check my Apple ID, find the cause of the error, and complete my enrollment in the Apple Developer Program as an individual. A phone call is welcome as well.
Thank you, Ekaterina
