Is there a "off/on" switch, or something, to banners that tells us that we need to Scout our up coming opponents.

I don't seem to get them anymore. With 6 teams, it gets a little confusing to remember who plays when. Could I have turned them off somehow??

No, the scouting banner should come up if you don't have any scouted plays during the midweek sim (it doesn't appear after the game stage, just the midweek) - if you're going into the scout screen between the game and the midweek sims then it will consider that you've done it, otherwise that should be the only condition that it's not appearing.
