AE/AF not working

The app is very neat and works pretty well but I cannot get AE and AF to work properly on my iPhone 6. It locks the focus and exposure pretty much all the time even when its set to automatic and I have to keep tapping the screen to update focus and exposure. When I was able to get AE to work the AF stayed locked. Another thing I noticed is that stabilization doesnt work as well as the iOS camera app. If all the bugs were fixed this would be an amazing app. Right now I can only use it if I dont need exposure and focus to change while recording.
