When loading it on the desktop Chrome there was a popup asking for my location. Like this:
But it was for the IP address or something to the Perspective session. I clicked allow and then my GPS coordinates were populating in the session properties.
Now from a mobile Chrome standpoint, it has never asked me that. In the settings for Chrome on an Android phone, you can see what sites you allowed and blocked access to your location and none of them are my perspective application.
