So I'm sure this has been asked somewhere previously but couldn't really find an answer. So, I bought my first Android device yesterday, Nexus 9 tablet. I configured it to my own Google account (no Google+ or Gmail), then updated to 6.0.1 and finally made a factory reset to make sure I have clean Android 6 install (as the device came with Android 5). Anyways, the device is now up and running smoothly but there's a strange thing in the Google Play store. It does not show that I would have any pending updates but if I search for Google's own apps, it shows that I can update them. Why wont they update automatically or at least show up as a pending update or do I really have to manually, one-by-one update every single Google app the device has pre-installed?
