I am writing because my Apple Developer account appears to be frozen or under review, and I have not received any clear explanation, email, call, or timeline. Around April 14, I submitted my app for review. At that time, the review team asked for more information about what the app did, and there seemed to be some confusion related to the App Clip. To avoid any confusion, I removed the App Clip and resubmitted the app with an explanation video showing what my app does. After that, the app was approved. About a month later, I upgraded to a more powerful computer. I gave my old MacBook Pro to my brother and started using my new computer to test new features in Xcode for my existing apps. Since then, I have been unable to proceed because of certificate-related problems. I contacted Apple Support, and I was told that because I bought and started using a new computer, my account had been sent to the Apple review team. I do not understand why this happened. I have not violated any policies, and I have not received any notice explaining what is wrong or what I need to fix. It has now been about three weeks, and I am unable to work on or test my apps. This has been an extremely frustrating experience because my account is effectively frozen, but I have no information, no timeline, and no way to move forward.Simply upgrading to a new computer should not leave a developer unable to work for weeks without clear notice or an estimated timeline. If this is expected behavior, other developers should be warned before they buy or switch to a new computer, because having an account frozen without explanation can seriously interrupt development work.
