I have to wonder if this has anything to do with Marketplace causing the sim to reset all assists to easy. Anytime since SU7 one goes to the marketplace these assists go to easy.
Microsoft put out a hotfix preview available to insiders to rectify that and other issues such as VR and Track IR problems.
I had to stop flying until they release a proper hotfix because I’m getting notifications of Marketplace updates. When I go there, sim resets to easy. Some ppl get this every sim start-up.
Just my 2¢
