<p>Obviously the backend is the same and it's covered by an aws certificate created by aws certificate manager. I think the problem is not the certificate because I think it is compliant to the new apple's certificates policy but I can't understand where the problem is.</p>

<p>Could you please help me?</p>

<p>Thanks</p>
