I have signed into Chrome on my desktop, and signed into Chrome on my Nexus 7, but sync is not enabled for the Chrome browser on the Nexus 7 for some reason that I have not been able to figure out. When I try to turn sync on, I get this message: "android system sync disabled please re-enable", but for the life of me, I can't figure out how to reenable it. When I try to reenable it, I get sent to the Dashboard, but cannot figure out what to do from there.
