stat startfile not saving on Oculus Go

Hi folks,

I started profiling my level on the Oculus Go.
I used “stat engine” to find my bottleneck. The highest values are the GameEngineTick with 34 ms and the RedrawViewports with 24ms.

To get further information I use the start/stopfile commands, that I launch on trigger pressed, but the files are not saved.

Are there some settings that prevent the engine to write to the internal storage of the GO?
