Truth be told: MSFS 2020 was released to the public on August 18, 2020. It was basically a beta application (almost a completely new flight sim designed from scratch) with many inherent problems. But as the Microsoft Corporation had a big stake in XBox, they were gung ho to release it. So now, 14 months later, the Asobo Team is still busy tweaking, fixing problems, and updating MSFS.
But as they say, patience is a virtue...
