Hi, I am currently testing the MRA APP. I am facing nearly the same issue, but when I have only one waypoint... I am searching for an address and want to navigate. The APP calculates the route, I press start and the APP is closing.
Today I have had that issue even when the APP is running several minutes, then crashing without any error message.

If you need more info please let me know.
