honestly, i think this has been discussed recently in their discord server (trust me, i agree it’s a mess and completely forgivable to have not found this).
bottom line, things changed with w&b when the dev moved pax and cargo loading to the efb. i believe he’s working on a solution to manage all of it from the efb but for now your issue is that the plane is loading weight in the efb and the cg is changing. once you’ve loaded the plane in the efb, open the stock w&b page in the sim and shift your cg so it’s more centered. i was berated in their discord for recommending this but unless you do this, you’re going hard nose up on takeoff with no indication how to set trim.
