When using HERE Maps as the mapping data provider, sometimes the route displays gaps in random places, see below.
I am on Safari 9.03, MacOS 10.11.3.
Note there is a gap in the route. I have not noticed any problems when editing or exporting the route when using HERE as the mapping data provider, so it must be just a visual glitch. Anyway, looks weird.
Yes, you see that very good. We are working on the Here Map.
Hope within a few weeks ready and with more options!
