Solved! Pedometers not working on Moto Z4

When trying yet another pedometer app (this one is called "Pedometer - Step Counter" I did this

1. My profile
2. How to fix the "stop counting steps" issue
3. Update settings
4. Next
5. Go to set
6. All apps
7. Pedometer - Step Counter (or whatever is the name of your pedometer)
8. Battery optimization
9. Click "ALL APPS" this is important
10. Click on don't optimize

So then I figured out how to get right to "Battery Optimization." Just go to settings, and type into the search "battery optimization."

My final solution

What I really like is Walklogger. So I uninstalled the other one, installed Walklogger, went to settings, "battery optimization," clicked "all apps," found Walklogger, and clicked "don't optimize."
