This is MSFS problem.
Please see the Users Manual, Part 1, p. 19.

VC VIEWS CONTROL PANEL

HOW IT WORKS:

•Make sure you are in VC mode view.
•Click on desired viewpoint amber square. The square turns red – GETS ARMED.
•Click on the viewpoint RED square to confirm your selection.
•MSFS flight should reload a flight with new viewpoint.

Note:

If the viewpoint does not change after the flight reload or MSFS does not reload the flight automatically, just reload the AIRCRAFT using MSFS AIRCRAFT > SELECT AIRCRAFT menu.
