Receive a notification in Spanish for your Nexus 7 (2013)? Read this immediately before updating
Since Google is now aware of the situation, we're confident that some resolution will come of this in the form of a new update. And if you do have the Spanish notification on the screen of your Nexus 7 (2013), fight the urge to tap on the 'Restart and Install' button. Nothing good can come from it, so you might as well wait for Google to push out the corrected notification in English, and announce that the update has a green light to install.

If your Nexus 7 (2013) is set for English but you receive this notification in Spanish, do not update your slate. Google is searching for a solution.
