When relaunching the flight on PC, controller settings are not saved. I have to change to bumper jumper and tune my sensitivities every time I launch which can be annoying if a crash happens.
If you are encountering issues during the flight, please refer to the known issues list on https://aka.ms/HaloSupportInsider and submit tickets for issues not present.
For general feedback that is not a bug or issue, feel free to use the pinned feedback threads at the top of the Halo Infinite forums
