Hey, i really appreciate your work! Unfortunetly older versions (even 18.104.22.168) of this app no longer supports mi band 2. Could you try to mod this app and i will try to test it on my mi band 2? You'll be my (and many other people) life saviour!
PS - I tried to modify this app myself, but unfortunetly i can't find a way to modify windows apps folder :/
