Keeps crashing won't save ride – Bike Computer - GPS Tracker Review

Installed this POS before Seattle to Portland and after crossing the finish line hit stop and the checkered flag. The app closes. Open the app to review the ride, and it still is in pause. I start and stop the tracker again, and hit the checkered flag. The app closes. The next day, try it again, multiple times and every time I hit the checkered flag, the app closes. It's still showing the data from my ride, but it won't end it and won't sync with Strava. No idea how to get support, it gets a single star. Hope you are relying on this for any important rides.
