VFR Map No Longer Maximizes

Anyone know how to fix this? It doesn’t matter the airplane it never maximizes anymore when you detach it from the main MSFS window. Was like this since SU5.

Same for me, but I don’t get any solution !!!

I found a solution. If you click on the black area to the right of the GPS tracking button between the button and the border of the window it will fill the window.
