On the previous version of Skype, you could send someone the location you were currently at. I had actually totally forgot about that as I only used it once to test it out.
It seems like the preview doesn't have the feature anymore, same with the desktop app. My guess is while they move everything to be more server-sided than peer-to-peer, some features got removed and placed on the back burner.
Send some feedback using the feedback app and hopefully it'll be put back into place.
