Unity app, scrcpy, low storage

Hello.
We have made an Unity app with some 360 videos and effects on top, sideloaded it on Oculus Quest. Quest is connected to a PC with a wire and Scrcpy streaming the user movements to a PC. The problem is that after a week of usage there is no more storage space on Oculus. When we browse the Quest folders on PC there are no unusally large amounts of data but zero space left. Does anyone have similar problem. Can it be scrcpy fault (maybe caching streamed video?) or maybe app problem (caching again?)...
