OffLine edition - Not calculating route

[mirko]

You are right, sorry. I wrote "post" instead of "thread".
I attached here the gpx file
  Routing-77a6.gpx (Size: 2.93 KB / Downloads: 171) where I have 4 points that are pretty far from each other. I'd like to have the routing between them calculated by the "insert point" functionality.
What happens now is that I select two points and the insert point functionality does nothing, as described in this thread.

5 years ago I ended up giving up on this

Thanks!
