My Dick's Sporting Goods app was connected to the Apple Health tracker. How do I disconnect the tracker, then reconnect it?

1. Open the Health app.
2. Tap your profile picture in the upper-right corner . 
3. Under Privacy, tap Apps. You can see apps that you already own that are compatible with Health. If you don't see an app, it might not be compatible. 
4. Tap an app and turn on the health categories that you want that app to track.

It should be there, try uninstalling the Dick's Sporting Goods app then reinstalling it.
