Of course! Thanks for getting back to me. FB16391677

I can confirm that api.sandbox.push.apple.com:443 has now the correct CA certificate, you can run the test above to confirm.

It's Jan 20 but Sandbox is still not updated with this new CA. Most likely because it's Inauguration Day in US. Would be great to perform this test as soon as possible. Let us know when we can perform the test.
