Health Mate not sharing data with Apple Health

OK, I've resolved this issue by following this solution I found in a related forum posting. Everything is working fine now.

Open Apple Health->Select the Profile icon on the top, right-hand side of the screen, select 'Apps,' and then select 'Health Mate'.
Select 'Turn all Categories Off'
Uninstall/Delete the Health Mate app (all of your Health Mate data will remain stored on our web servers)
Restart your mobile device
Reinstall Health Mate, and log in with your Health Mate credentials (your Health Mate data will be downloaded to the app)
In the Health Mate app, select 'Profile.' From there, select the Apple Health logo (white background with a red heart)
Select 'Turn All Categories On' (or manually select any metrics you wish to sync) and then select 'Allow' from the top right-hand side of the app.
You should now see a green checkmark on the 'Health' icon in the Profile of the Health Mate app, and both apps will begin syncing again.
So that Health Mate data is transferred to Apple Health, ensure that 'Background App Refresh' is enabled for the Health Mate app. To do this:

Go to 'Settings' on your iOS device
Select 'General'
Select 'Background App Refresh'
Ensure the slider to the right of 'Health Mate' is green
Keep in mind that at present, lean mass, muscle mass, water mass, and bone mass do not sync with Apple Health.

After after going through this process several times with no change in sharing data between Apple and Health Mate, I found this information that made it work:  

Here's how to choose the sources that Health uses first:

1. Open the Health app, then tap the Browse tab.
2. Tap a category, then tap a subcategory.
3. Scroll down, then tap Data Sources & Access.
4. Tap Edit.
5. Touch and hold the Change Order button  next to a data source, then drag it up or down in the list. 
6. To turn off a data source so that it doesn't contribute any more data for that category, tap the checkmark next to the source.
7. Tap Done.

If multiple sources contribute the same data type, then the data source at the top will take priority over other sources. Any new apps or devices that you add go to the top of the list automatically, above your iPhone or iPod touch.

Move Health Mate to the top of the list.
