Unfortunately, when prompted for the install of 1.4.20.0, MSFS 2024 would not start up without going into safe mode first. So I did.
Then, I forgot that safe mode disables all of your third-party addons until you go back and fix them, yourself. I have over 800 addons. (In previous posts, I said 600, but I did some counting and am amending my number.) I really don’t want to have to go through all 800 and enable this one and not keep that one disabled. It is a huge hassle. Does anybody else find this to be a huge UX problem?
