The overall quality performance of the app gradually deteriorated since the other features came. I have this really nasty problem about moving/hovering overlays, audios, texts, and effects, where it just teleports to somewhere instead of just staying place in the area I want it to be. I've tried resetting my phone and install/uninstalling the application just to somehow fix the problem, but nothing seems to work anymore. And no, my device isn't the problem.
