I've had my Nexus 6P for about 2 months now and have always noticed that the "User" icon in the upper right part of my notification shade when I have it pulled down just has circle with a silohuetted figure in it. At first I just figured this was something that Google must've changed for Marshmallow, but I've recently started seeing screen shots from others and have noticed they have what appear to be Google Profile photos showing in this spot (which I had initialy assumed would be the norm). I of course have my Google profile setup with a profile photo, so I'm wondering if I may have done something "wrong" when I was setting up my phone initially. When I go into the accounts from the notication shade, I see my main account (though it's only listed showing my first name) and then an option for Guest or to "Add user"... From the list view of the user accounts, when I click on the option showing my first name, it only pops up a screen to change what's shown there and there doesn't appear to be anything more available through settings on this screen to really allow me to do much. Is this somehow a "different" profile from my true Google/gmail account profile?!?
