Hi everyone! On my iPhone 6, the video that goes along with the workouts lags behind (it seems like it's buffering and means that the moves are jumpy - it's basically like seeing 2 screenshots for crunches, for example, simply flipping back and forth). On my old Android, it didn't skip, so it seems to me that there is some sort of issue with compatibilty, maybe? Does anyone know of any ways to fix this? Thanks in advance for your time!
