Wirelessly posted (curv 8310)

I have a 8310 running 4.5 and my girlfriend has a lg incite using windows 6.1. My ? Is when I try to see where she is or her to see where I am during the day it never seems to update. It always shows us home on the others phone. Mine shows me at work or wherever I am on my phone but on hers it shows me at home. I'm sharing my location. What am I doing wrong?
