I made my first 'proper' flight in MSFS 2024 today, continuing my Duke adventures with Air Hauler 2. I'm planning to switch from 2020 at last as 2024 seems to run well enough for me now.
Although I use a little utility called AircraftState to help save as many variables as possible in any aircraft, I was interested to see what happened with the Duke's own state.cfg file after reading of the issues here.
I loaded into the sim at about 16:00. When I landed and was ready to quit at about 17:20, I went into the directory where the state.cfg file is saved. It still had a timestamp of 16:00 on it. I tried toggling an option or two in the tablet in case changing a parameter could trigger it to update and save. Nothing happened.
So, I ended the flight. As soon as I was back at the world map, the state.cfg updated with new fuel values and Hobbs hours etc. So it can/does work in some cases. I'll be keeping an eye on it for sure as I get used to 2024's foibles.
