COOP/ Multiplayer Mission Problem

[[J4F]Thunder666]

hi,

I have reference to the Declaration PDF "missionmakingfordummies.pdf" trying to create a coop mission which is playable with friends online.
Unfortunately, I have not succeeded, so here are my questions to the topic.

First, I have created 2 armies (UK / Ger). So far so good.
Now I have created 2 spawn points, red and blue.
So it was explained in the PDF. Then just follow the waypoints for AI topic.

So I saved the mission and started as a server. In the lobby, I can now choose a side (red / blue).
But I can not select an aircraft, since none is in the list. What is the spawn points are good then? If not for the player?

Next, I added 2 aircraft blue. After selecting the site, I can now select a plane in the list. But I can not fly again.
The plane is an AI. If I "fly" on press I can see her no more.

What am I doing wrong?

Nowhere explained in the PDF I have to first create a player aircraft?

Do I create a player aircraft, although I can get on a plane. But how can other players connect? One can only select a plane for players!?

Have tested it with a friend. I was able to fly with the "player aircraft. He could not select any.
In addition to others, waypoints and other objects are not visible on the map in the briefing.

Am very confused and ask for help
