"In the Apple Developer app, after completing identity verification, the 'Register Now' button remains grayed out, and I cannot proceed to the payment page. I'm not sure what I did wrong, but this issue is preventing me from publishing my own app. I hope Apple can help resolve this problem. I encountered a similar issue many years ago, and customer support said it was complicated and suggested re-registering, but that didn't solve the problem back then. This time, I truly wish to have my own developer account."

Perhaps I made the earlier historical description a bit too complicated. Let me simplify it now. Due to the outdated version of my previous iPhone, I purchased an iPhone 17 yesterday. The system version now meets the requirements, and I registered a developer account. After completing all the steps—providing my ID card, address, and facial verification—I returned to the developer account only to find that the "Registration in Progress" button is grayed out. I am unable to proceed to payment to become a developer member.
