Help Trouble with Copilot navigation app

[ron4adams]

I saw an old thread related to copilot not starting on a Samsung. As was described copilot was functioning fine for several months. The when the start up key was engaged the page with copilot name on a black background opens for several seconds and then the tablet reverts back to the home page. The app appears in the background, but never opens. I hope someone has discovered the problem and can offer a solution.
