My G-Mail app is not syncing. I am running 8.6.3. In settings I made sure my gmail account is ON and the Gmail box is checked. I can get my emails just fine but when I archive them they only get archived on the phone. When I log into Gmail on my computer all my emails are still there. Any suggestions? Is this related to the facebook syncing issue? If I delete emails on my computer they will not show up on my phone. Seems like a one-way sync. Weird!!!!!
