Just a quick update as I am able to be back online where I’m staying tonight.
I had created one route for each day on my trip. The route for Day 1 always gave me the reported problem — however, the app has been working much better with the routes for the following days. I saw the problem occasionally but it eventually worked on these other routes. My guess is that the problem is related to routes that go over the same point more than once — just a wild guess here!
Thanks for replying.
