Could be it hasn't synchronized... or you're just not connecting to the same data server... or they don't deem it to be the best view for your area and device.

For example, the one they always show for my area is from September 2009. But if I go into Google Earth, I can also see satellite views from October 2012 (nowhere near as clear) and September 2013 (dark and low resolution). Even the Street view doesn't default to the most recent available for some reason. Interesting going back to 2002 and seeing how undeveloped my area was then.
