I'm aware this isn't a place intended for troubleshooting questions, but when one adds a read-only Google Sheet to their drive, doesn't it just make a shortcut? I clicked on the Drive icon as shown in the tutorial but the document is still read-only, and the app says that it isn't in my Drive. I tried making a copy with the same name, but no dice either. What am I missing?
