Thank you so much for your explanation, I don’t fully understand the technicalities but get the overall picture. I will approach MyRoute-app about it as they have very good customer service.
Since raising this issue I have found two other locations where the same thing happens. These are both dry ‘flood’ fords where the road remains dry in all but the wettest times when it’s allowed to flow both under and over the road. No barriers on these locations but I’ll advise MyRoute-app of all of them in case they have some setting blocking water crossing.
Thank you again for your efforts to resolve this.
