My Safari Web Extension got rejected with the following reason: "Guideline 4.0 - Design The user is taken to a new Safari window or tab to sign in or register for an account, which provides a poor user experience." Is this right? First of all Design guide line 4.0 does not seem to mention antyhing about this topic. Second, I've seen many, many web extensions that opens a new tab to let you sign in or register. Including top recommended ones like Grammarly, PayPal Honey and Pocket. The review also mentions: It is acceptable to take users to the default web browser for some sign in or account registration options if ASWebAuthenticationSession is used for the session. That does not seem right either, since that is primarily designed for native apps. I'm pretty sure the extensions I've tried that open a tab for authentication does not use that. It is like my Safari Web Extension is being reviewed like a Mac OS app. What am I'm doing wrong?
