Yes, multiple simulators can be used for the same profile, and progress will continue to be tracked. For example, in my main Fly the Line profile, I typically complete flights using a mixture of MSFS 2020 and MSFS 2024, and the progress continues to be tracked at the end of every flight. On other profiles that I use for testing, I have used a mixture of MSFS 2020/2024, XP12, P3D V5 and FSX:SE and the money and XP I earn at the end of the flight is always added to the profile, regardless of which simulator is used.
Hope that helps.
