Thanks for the suggestions.
From the patch notes;
4 hours of existing flight time in a non-Discovery flight (free flight, landing challenges, bush trips, etc.) are required to display the event on the homepage, which replaces the Discovery Flight shortcut.
I just completed the Airlines training and still not showing. Pretty sure I am pushing 4 or more hours in the challenges etc. It is just not showing for whatever bugged reason.
I am surprised no one else has mentioned this issue, surely I can’t be the only one.
