Always been a nagging issue but I’m working through a particularly aggressive instance of this right now.
Two different wireless mice, plugged into every possible USB port on my Series X, with and without ANY additional peripherals, tried custom mouse profiles as well as default, and just completed a full uninstall and reinstall of MSFS Game of the Year edition. No clicky, no happy.
Quick Resume trick has worked in the past, no dice now.
Uninstalled all World Updates and every add-on there is (I never had many). Nope.
Hard restart on the Xbox, hard restart on the game, same deal. I just can’t play MSFS now and I’m at a loss.
