'Sign In With Apple' on CNA's embedded browser

This only works if there is already a valid (cellular) internet connection before actually signing onto the Wi-Fi network.

The native component that handles the on device sign-in (e.g. using finger print of Face ID) needs a fully established internet connection to do so or will otherwise show an error, after not responding to input at all for over a minute).

Is there any way around this limitation? In our scenario, we have whitelisted the following domains which has allowed for Sing in with Apple to work from Safari, but it always fails using the native CNA:

• account.apple.com
• appleid.apple.com
• appleid.cdn-apple.com
• idmsa.apple.com
• gsa.apple.com
• mzstatic.com
