"Hi.  As you gathered,  the green up arrow means 'needs syncing' and the screen activity indicated that things were pending.  An immediate sync isn't guaranteed - all sorts of things can interrupt the connection,  from local traffic to the server just being busy (there are another 200M users syncing out there somewhere).  - I just scared myself and worked out on average that's 5 syncs every second throughout the year... \n\n\n\tThe moral being:  If at first you don't succeed...  try again later.   "
