When W10 was first downloaded to my Surface Pro 3 I poked around the various screens and ran across a screen/app/settings location that allowed me to locate my mobile phone.
The phone information was shown on the screen, and I know that I didn't enter them. The screen also showed a small map with a pin where my phone was located. There was also an option to have the phone make a sound, which I tried and it worked.
The problem is that I cannot relocate that screen. Asking Cortana simply took me to Bing search results for various service to find phones, and apps to download.

Does anyone know how to navigate to that screen?
