App is currently broken

Since the most recent update I can no longer lock my phone and then open it back up to the app without it ceasing to function. I have a iPhone 6s and would take video. So when on the video recording screen I would often lock my phone then walk around until I needed it again, then unlock, and it would open back up to the recording screen and work fine. Now it locks up every time if I have locked my phone then open back up to the app
