After getting Marshmallow on my Nexus 7 (2013), I can't transfer files from the Nexus to the computer using USB. The charging lightning-bolt shows up, but no window opens on the computer, and when I go into "computer" in Windows Explorer, the Nexus doesn't show.
After some online searching I found the "Select USB Connection" option under Developer Options in Settings. The consensus was to change it to "MTP" but it was already there. I changed it to "Charging Only", then back to "MTP". Nothing. I've done what everyone says to do - what now?
