Rarely starts

When I am able to get the program to respond to pressing the start button, its a great app that captures a variety of metrics. The watch app rarely if ever responds to the start button. Ive had others try to start the app in case I was missing something, and they couldnt get it to respond. Also tried uninstalling and reinstalling to no avail. The same for trying to start on the iPhone (7 Plus). I hope this will improve because I really like the metrics it captures when it works.
