"Bug: no km counted."

#PokemonGO: Yesterday night I dit a 7 km walk with other 3 player. 2 of them has no problem in km update, for me every time the game update the km it adds only 0,1 km instead of the usually 0.3 - 0-4 km. But I found a way to bydpass the problem: if I close and re-open the app they add the missing km. The surprising thing is that the last friend has no found a way to add the missing km, so at the end of the walk the app countend only 2 km. Is there a way to bypass this annoying bug? via /r/TheSilphRoad http://bit.ly/2EWgJ3m
