Huh? They have acknowledged issues and are continuing to do so here: - Known Issues - and Microsoft Flight Simulator Known Issues Tracker - Microsoft Flight Simulator - I suggest you check it out, as it’s last been updated today. There’s absolutely no need to rollback so much progress when they’re able to highlight the isolated issues players are having and correct them as soon as possible. If you haven’t watched any of the livestreams with the developers, I suggest you do so. They are very passionate about MSFS and want to grow the platform into something really incredible.
I sympathize with the players being disrupted due to the latest patch, but there are also a lot of players not having issues at all.
