Galaxy Edge freezes on lock screen while using Fit Bit activity tracker

[AC Question]

Hey all,

I've had my Edge for a month and a half now and my fitbit for a month... I've been having a very frustrating problem with my phone not letting me through my lock screen when I'm using my Fitbit activity tracker (GPS Run/Walk/Bike ride tracker).

I run everyday with my phone and this app and it's frustrating to have to reboot my phone to get through the lock screen. Is there anything I can do to fix this problem?
