I noticed yesterday that I had 4 apps that supposedly have updates. None of them are sideloaded--Aqua Mail, Dragon Fly (Free), Snag Films, and Redux. I selected "update" and the icon them turned to "updating" but never does anything. I tried it again today, but same results. I unplugged/rebooted the Co-Star and it still does it.

The only other thing to add is that despite Google Play showing those apps have updates, I haven't received a message in the notification bar informing me of updates.

Any ideas?
