I have already taken two flights with the A321neo and then let the autopilot+ fly—just as before (successfully). Now since the update, when the ETA is 30 minutes and I open the simulator, the flight display for the route no longer follows even though I have it active. I have created the flight plan as usual in the IF, not SimBrief.
The plane just suddenly leaves the route without a trace, no matter what I do…
