I am a recent convert to android from apple and have bought a nexus 7 which I am really impressed by. I have an issue with the keep app though. If I put a note onto keep on my Mac or Moto G phone the notes appear on the other device but not on the nexus. When I first installed keep on the Moto G notes from the nexus appeared on it but subsequent notes or edits don't seem to go from the nexus to other devices or vice versa. I can't find any settings to change. Any ideas why this could be.
