Career Mode Employees? Crew On? How does it work?

I really don’t understand how ‘Passive mode’ actually works within the career mode.

I have created a cargo company, brought a plane and have set the mode to ‘Crew On’ and have only flown ‘Employee’ missions but still not had any income even though I’ve completed a number of ‘Employee’ flights.

According to the FAQ webpage - https://flightsimulator.zendesk.com/hc/en-us/articles/17123300945052-Career-mode-FAQ

It states the following:
Q: How does the Passive Income Mode work so I can earn more income?

A: When “Crew” trigger is set to ON, you need to launch missions with other airplanes or in Employee mode if you only have one freelance aircraft to trigger “passive income.”

Passive income calculation is based on how much time you spent in one or more career missions without using aircraft with “Crew On.”

I should be generating passive income with just a single plane as stated above but this isn’t happening. I created my company on Monday so I would expect to have some income by now.

Does anyone else have the same issue? Is this a bug or do I just not get it.
