Hey no problem. I just followed your steps on my phone. I set it to the Target closest to my house.
To be clear to everyone. You have to open the Dev tools on your phone. You can google how to do it on your own phone. I had to go to "About Phone" in my settings then "Software Information" then tap "Build Number" 7 times.
Then in Dev tools I went to "Mock GPS Location App" and added Fake GPS which I downloaded from the Play Store. I set the app to the Target closest to me and followed theSLAYER's steps.
I love this btw. It might be the easiest way to get Events ever, I live really close to a Target so I didn't even have to do this.
