This problem seems to be quite common and affects both Xbox and PC. All the more reason to take this into consideration, but it doesn’t seem to bother Asobo too much.

For my part, I decided not to put a dime more in add-ons or DLCs until the fundamental MSFS bugs are fixed, and this one is on my list (just like those relating to joystick and mouse on Xbox).
