Different people working on different issues. Probably a substantial chunk of the team are 3d artists that built planes, and all 3d assets in the game. You want Asobo to fire them or force them to learn to code? Or assign them to Q&A without real expertise in their area doing what is not supposed to be their primary job?
Some people assume that if you pour more people from other things to a specific area, everything will go faster and bugs can be fixed. That is not true. Asobo is hiring currently for additional specific positions related to coding and related to flight dynamics. Maybe a bit too late, but it seems they were waiting to see if MSFS will be a market success and now it seems they have resources to grow the team. Just give them some time.
