Webcore mobile app not picking up latest location


I have a piston I use to collect location info from each member of my family. It uses the webcore mobile app installed on each person’s phone. It had been working well until one person uninstalled the mobile app. I’ve reinstalled it and granted it permissions to get location from the phone and it still does not return the actual location. It just returns the last location when the app was uninstalled. Any idea how I can fix this?

FYI - I’m not able to share the piston as it includes private key info.
