American Airlines App (IOS) blocked

The American Airlines app does not fully function when on a mobile connection while NextDNS is active.  I created a profile with everything disabled, but it still fails to pull up details on flights or accounts.

Disabling NextDNS fixes it while on a mobile network.  Switching to a Wifi network fixes it with NextDNS enabled.

It seems like a problem with the combination of the app, NextDNS, and a mobile network.
