Description
I am reporting a logic inconsistency regarding access permissions for legacy WWDC video assets hosted on download.developer.apple.com.
When attempting to access a specific video URL (listed below), I am presented with an error message stating: "Your account can’t access this page... make sure your Account Holder has agreed to the latest license agreement."
However, I have observed a reversal of the intended logic:
1 The Issue: When my account is in a state where the latest license agreement has not yet been accepted, I am granted access to the video file and it downloads/plays successfully.
2 The Inconsistency: When the license agreement is accepted and the account is in good standing, the system triggers the "Your account can’t access this page" error.
This suggests a possible "negation" or logic error in the backend code responsible for verifying the Account Holder agreement status before serving protected content.
URL in Question:
Steps to Reproduce:
1 Log in to a Developer Account where the latest License Agreement has not been signed.
2 Navigate to the URL above. Observe that the file is accessible.
3 Log in to a Developer Account where all agreements are signed and up to date.
4 Navigate to the same URL. Observe the error: "Your account can’t access this page."
Expected Result: Access should be granted to active members who have accepted the latest agreements. Access should be restricted (or prompted for signature) for those who have not.
Actual Result: Access is denied to compliant accounts and granted to non-compliant accounts.
