Hello there... i bought this weareable because is one of the few compatibles with WP8.1
After laste Leap manager Windows phone app upgrade i had a problem: it notify me a firmware upgrade but was not working...
So i decided to upgrade by Android app. it worked, but just after i switched from italian (my language) to english.
The leap now have fw 3.4, instead ofo old 1.36.
Problem is that now Windows Phone app (that is in italian) is not connecting wth the device... BT is acrive, Leap is connected, but app is struck on "Connecting..."
Obviously, under android is working, italiano or english does not matter anymore...
