Localisation of a player doesn't work

Hello,

I tried to localize players using the option in the menu when 'm in the profile of a player, but I'm only getting a blank map and after return to my own location on the map. So this doesn't works for me.

Other players from my gang tried it and it works fine for them...I'm using an iphone 4 with the Dutch version of the game.

Anything to do about it?

P.s. the other players that tried it have the French version of the app.
