How do I make a scenario game?

The process of making a scenario seems to be extremely different from the previous processes to make one. I can't seem to make a scenario and I was wondering if anyone can teach me how to make a scenario, just like the ones in the old days.

I go to the scenario tab, and I click the "create map." (I have no idea if this is actually the one I press. (I AM A PREMIUM) Then I get to a page with all the maps and borders, but I can't seem to place any units or produce anything like the old scenarios.

Did AW take out the creation of scenarios completely, because I can't seem to make one.

Suppose I am Spain, and I want to strategically place the units against France, like the Spanish Armada. Can anyone just briefly go over the points in making and producing units? (also includes publishing the map and making it available for other people to play)

Maps and scenarios are not the same.
A map is a map, you can draw the borders to make countries, set the reinforcements, create new units (You can adjust attack and other things), etc.
In scenarios you just add events (removing or adding units on the map), adjust income, make walls, etc.

To make a scenario, click the map you'll use for the scenario (If you want the default map, just select 'World Map'), then click 'New scenario/preset'.
