Hopefully someone replies soon regarding those add-ons. I’ve chosen to limit my experience with add-ons until the game is more reliably stable. I only use Marketplace stuff and liveries right now. It gives me anxiety waiting for stuff, but I want to limit my troubleshooting time.
MSFS has always been mandatory “study level” for the base platform - just to get it to work (at least in my past experiences). The fact that I could play it, without editing any Windows or game files, when I first bought it makes me appreciate that we live in the best of times - for flight simming.
