What is the lock icon next to the Google Play store icon in my notifications?

[Android Central Question]

The padlock showed up this morning next to the Google Play store icon in my notifications. When I click on the play icon, it won't go to it. I went to Play through the icon in apps and there was nothing waiting to be down loaded and I couldn't figure out what the padlock means and can't make it go away.

Welcome to Android Central! You were able to open the Play Store successfully from the App Drawer, and it worked normally? Which phone do you have?
