Vitality App does not work/can’t be fixed?

I have been registering my daily workouts on the Health App and Discovery Vitalty for years. For the last two years I get a daily error message:’no new data’, despite my workout. Advice from Discovery staff is to delete the App and re-install it. This works very well; but is cumbersome and not the way an App should work! My wife;s App works perfectly, but I am expected to delete and re-install. It requires a fix; but Discovery is unresponsive!
