I'm back from vacation next week and can't wait to start a great career with "Zero to Apex"; I've heard amazing things about it, and from the videos I've seen, it looks fantastic. I've missed you, Automobilista 2.
Same app in the stream I mentioned. I have a feeling the app might be changing it for some reason. I don't think I've ever had an issue with the setting in vanilla, but on the other hand it's been ages since I've actually used it. I mostly play championships these days. Small sample size for this hypothesis though.
I've done some AI assisted reverse engineering of the app to run it on linux (and to reuse the DLL to do stuff like tweaking FCYs for instance, haha). Basically the app overrides the AMS2 setting, when you set it off it uses the AMS2 setting. You need to disable yellows both in the career app and in the game to avoid them.
