How can you tell which sections TomTom thinks are unsealed?

The entire Oalen Ford Road in NSW has been sealed for over 2 years. TomTom think parts of it aren't so routes you round it (somehow Google/Apple all know its sealed). I've tried reporting it through MapShare with no change (Yet).
Question - where is the legend for the MapShare/MyDrive map? How does TomTom display which bits it thinks are unsealed? I think its the 'uncoloured' roads - but nothing seems to confirm that. Screen shot attached.

Hi, I'm trying to find the exact location. Could you name some start and end points (coordinates) where the routing goes wrong?

Canberra Monash -> Tomerong, NSW (as an example)

Thanks for the information. Strange, it uses that road correctly when forcing a via point on the route. But for another route, it chooses this road somehow while another one is much faster. See the screenshot below. Somehow the routing algorithm makes some mistakes here.

Im glad you’re seeing the same behaviour I am. The routing algorithm is definately making mistakes. It chooses the Oallen Ford Road (which is the fastest) when travelling to *some* destinations on that route - but then avoids it when travelling to other destinations further down the same road (even though that makes the route slower). I wish there was some way to see the ‘decision tree’ that the algorithm uses.
