Before reporting the bug, I appreciate you to add 'combined acceleration' feature on Racechrono!
Today I found 'custom storage settings' doesn't work properly in Android version 7.x, the setting in Android 5.0.1 (galaxy s4) works fine though.
In 7.x, when I set the custom folder as external SD's movie paht (~~/DCIM/Movie), it doesn't show 'Custom storage' in the video link menu, but it only shows 'External storage' which is default path in external SD (~~/com.racechrono.pro/files/movies/racechrono).
Weird thing is that if I set the custom folder as external storage path (~~/com.racechrono.pro/files/movies/racechrono), it shows Custom folder and External storage both.
Would you please check what the problem is?
