The main problem is affordances. In old days, users were expected to be new bees and needed to be get productive fast. So menus explicitly featured keyboard shortcuts, apps had status bar telling you what was happening, there were even main menus that told you everything you can do with app. Then UX designers thought they should be clever and make this a game for user so they eventually figure out how to do X. Some such initial games produced "aha!" moments and UX folks took that as signal for doubling down in the name of minimalism. Now apps rarely have menus or status bars or even toolbars. Users are expected to struggle a bit to get their "aha!" moment. Sometime even critical functionality is kept hidden under weird actions like triple-finger squeeze. It's horrible for users but apparently UX guys think they are doing cool shit.
