I can't seem to get my gmail to synch. I have a nexus 5 and a macbook. I receive most of my emails on my phone. I will read them and then delete them from the phone. However when I open up the macbook to use it, I have several messages that are marked as unread that I had received on my phone earlier in the day. Even waiting a couple of minutes doesn't clear it. Anyone know how to make apple and google work in harmony together?
