I've installed Google Drive on my pc and Nexus 7 and placed a Google Spreadsheet doc into the drive on my pc. When I use my pc browser (Firefox) to view the googledrive.com website, the doc is there.
However, when I open Drive on my Nexus - nothing. And when I view the googledrive.com website on my Nexus browser (Dolphin) it's empty too. Not a doc in sight.
I'm getting nowhere with Google Help on this issue - they keep telling me to click on options that don't exist on the Nexus or telling me to do things on my android phone (Don't have one!)
ETA: Okay, I've decided what I wanted to do just isn't worth the hassle of trying to figure out Google's accounts/apps systems. It seems designed to be as obstructive as possible. :P I've given up and deleted Drive.
Thanks for your attempts to help though - greatly appreciated!
