I noticed this a few days ago, but wasn't sure if i was just tripping, but it keeps happening. Every time i reboot, it of course asks me if i want my External to be mounted as Internal. I say no, keep it as removable, and it exits to the storage settings screen where I used to enable the option to access shield folders on PC at that time, but lately, it's been surviving the reboot. Is this happening for anyone else?
