I am currently unable to submit a support request or request a callback using my primary company developer account.I am receiving a persistent validation error stating: "This email address isn’t valid. To update your email address, visit account.apple.com." This is incorrect as the email is fully functional and I can receive emails from Apple on that address and its been years using the same email. This error is preventing me from sending any message to Apple support or requesting a call.

Title: URGENT – Apple Developer Account Issues: Invalid Email Error, Missing Invitations and Unable to Contact Support Hello Apple Developer Community and Apple Support Team, I'm reaching out here because I have exhausted all other options and urgently need assistance. I am the Account Holder of our Apple Developer account, and we are currently experiencing several serious issues: Unable to contact Apple Developer Support: Every time I try to submit a support request, I receive the following error: "This email address isn’t valid. To update your email address, visit account.apple.com." My email address is valid: My primary email *** is correctly registered in both my Apple Account and Apple Developer account. The mailbox works perfectly, and I receive other emails without any problems. Developer invitations are not arriving: Invitations sent through Apple's developer services are not being delivered to our email addresses. Endless sign-in loop: When trying to accept an invitation, the page displays "Sign in to accept your invitation." After signing in, it simply reloads the same page. App distribution problems: We are also having difficulties distributing our iOS applications through TestFlight, making this situation particularly urgent. I can successfully sign in to App Store Connect and access our applications, so my account itself is accessible. The biggest problem is that I cannot even contact Apple Developer Support to report these issues. I am stuck in an endless loop with no way to get help. I have verified my account information multiple times, but nothing has resolved the problem. Could someone from Apple please investigate this issue or advise me on an alternative way to contact Developer Support and open a support case? I would greatly appreciate any assistance. This is affecting our ability to test and distribute our applications. Thank you very much! Best regards, Marian Patak
