Hello, I am unable to submit a support request because the Apple Developer Support form displays the following error: "This email address isn't valid. To update your email address, visit account.apple.com." My primary Apple Account email address is correct and is already configured as my primary email address. I have also tested the support form in a private browsing window, but the issue persists. Could you please investigate why the Developer Support form rejects my primary Apple Account email address? Thank you for your assistance.
