Hey guys! I believe I've found the solution to successfully enrol for the Apple Developer Program. This is for all of us who have tried enrolling and waiting in vain for the confirmation email from Apple after the acknowledgement email. First, you should know that the whole time I was attempting to enrol I was using my iCloud account and I was trying to do so via my MacBook with the browser. I tried both Firefox and Safari just to be sure it wasn't a browser thing. Then a thought came to me... since I knew Apple also had an Apple Developer app on its store that according to its articles it claims can be used to enrol... I chose to go for it, and this time I opted to enrol with my iPhone for good measure... I downloaded the Apple Developer app... logged into my iCloud account and attempted to enrol. However, this still didn't work. The message said that I couldn't use that email to enrol... And so I signed out and opted to use my Gmail account and voila! I was able to enrol!! The payment went through successfully! I received the SMS notification from my bank and I also got the subscription confirmation from Apple. That's how I did it. I really hope this helps someone 🙏.
