I'm trying to open `file:///mnt/us/` in the web browser but I am getting the "Invalid Protocol" error... this is a brand new Kindle Basic (11th gen) running 5.16.8
I find it weird that I am getting this behavior because I'm pretty sure I had it working at some point yesterday (I have a couple Kindle's I play around with so I am not 100% sure it was with this one).
