Siri, "I don't see an app named"

Every since updated my iPhone 5 and iPad 3 to iOS 6.1.2, Siri will not launch any apps except Apple own. After every other request, Siri replieswith the  response, "I don't see an app named". 

Can someone on iOS 6.1.2, please 

try to open a non-Apple app with Siri. 

Please report your results.
