We get this message after distributing a Safari extension from xcode to itunes connect. Any idea what it means and what should we do to solve this error?

I converted an extension from Chrome to Safari using: xcrun safari-web-extension-converter All works except for one thing: when trying to access the localStorage or sessionStorage from background script I get: SecurityError: the operation is insecure. It works in all other browsers (chrome, firefox, edge) - but not here. I hope that the solution is to turn on some flag in the xcode build settings and not to try and implement some native swift code - which I (and many other developers) will not do. Any solution?

Sandbox payments - iPhone>Sandbox>Subscriptions is empty, after I did a sandbox payment. Why? My Apple tester sandbox account email is not an accessible email address (fake), so how can I bypass two factor authentication with it?
