@Peter-Schiefer said in Issues, system automatically skipping waypoints and therefore changing the whole route:
If you deviate from the route for other reasons, the system always calculates the next possible suitable point on the original route, whether this is 30 meters back from a petrol station or a U turn around a block of houses
Well the most import difference here is that we, in general, when using MRA next are navigating a pre-planned route using those waypoints! That is very much different from an a2b route as we generally use in car nav systems or similar! You tell the nav to route you on a pre-planned path, any other system as you refer to is simply instructed to guide to from start to end, no matter the roads it seems fit to do so! This is a major differences in the two distinct scenarios.
Your answer seems to indicate you've misinterpreted my post as a negative critique to @Thomas-Scharrer which is definitely not the case.
I was merely putting forth my opinion regarding the statement that it does not make sense the app is autoskipping waypoints when deviating from the route.
Now Thomas mentioned specially in the post above, which came before this post from me as a response to yours haha, that his deviation from the route was only a few meters. That makes it a whole different story. 
Yet, the mechanism in general, still holds.
@Peter-Schiefer said in Issues, system automatically skipping waypoints and therefore changing the whole route:
Since MRA only takes route closures into account in the initial calculation or already in the planning stage, if stored in HERE, automatic skipping should not exist at all.
I never referred to the traffic information from HERE nor the handling of the app regarding that info. I mentioned roadworks as a practical example of things you can encounter during your trip, that make you explicitly deviate from your meticulously pre-planned route.
