Google Play Services - Version Request

I updated my Google Play Services and I recently started getting a message in Google Fit that Activity Detection is off. I click on it and it acts like it will take me somewhere and it never does. Same when I try and view the Google Maps Time line. When I go into location settings Location Services is missing.
Any ideas?
Can I reinstall Location Services somehow?
Can I downgrade back to whatever version of Google Play Services that came on the phone?
