Hi,

I've mounted various games from /storage/emulated/0/Android/obb to /storage/usbdisk

It works fine for playing the games, however I cannot update them. I get a permission denied message and looking closer into it, I am mounting with user and group 1023. I can however, create the files directly on the OTG whilst the foldermount pairs are mounted.

Here are my mounts:
