Unable to adjust the weather on a recorded flight

When I want to do a long flight, I save the flight in .flt format When I want
to resume my flight, I load the flight I saved. At that moment I can no longer
modify anything in terms of the weather. (time, cloud, live weather, etc…)
What can I do ?

These kinds of questions you can check the forums first. This is already a
known issue. <https://forums.flightsimulator.com/t/change-of-weather-and-time-
