Reinstalling won’t help. In AAU1, they aligned the operation of the in-sim navigators (GNS530, etc) to act as they do in the real world. Under the previous guise, using the world map would inject fake user waypoints to smoothly connect the route (or arrival) to the approach, but that’s not really doing an ILS, because ILS (VOR, GPS, etc) approaches are all about the procedure - bypassing it becomes “ILS-ish.” At the same time, when doing it the “right” way, those fake waypoints caused very erratic behavior.
I’m not sure if they’re going to find a middle ground that works for people looking to have it behave correctly and those looking for a turn-key method, but I suspect that fixing the underlying issues with the nav data and the way the program uses them was the first step and there will be more to come.
