You can try opening up the Google play store and then search for the Google Play services application and make sure it's up-to-date, then open the settings for your applications and scroll down to the Google Play services application and clear the cache of the application, if these steps don't work open the settings for the smart lock feature and turn off the on-body detection and then back on next check the settings for the smart lock location services it's possible that it's not picking up your location and needs to be reset

As you know, some Google services might not be available in the Beta SW as it is not certified by Google. If you continue to have issues, please use the latest Samsung Members app to submit an error report.
