When typing a manual activity like for example swimming to the app it alters the distance input on it's own. If I have entered 3 km, next time I open the app, the distance is 30000km.
I have the same problem using iphone5s, ios7.1.1, connect-version2.1.1
Some weeks ago I started a question to the support.
Today I have send the next mail to the support.
I can't believe that it is a proplem to solve it!
