Navigraph maps not loading on iOS

How to resolve Navigraph not loading.

If your Navigraph maps aren't loading, turn off "Prevent cross-site tracking" at Settings > Safari > Prevent cross site tracking.
You'll need to kill Safari completely then reopen it and refresh the EFB page to get it to show.
