Siri's "Take a Selfie" no longer working

This just stopped working for me, not sure if it was the update or not (I'm on 15.5).

It used to bring up the camera in front-facing mode by saying "Siri, take a selfie".

Now it brings up a Wikipedia article about taking selfies :(

If I say take a photo it brings up the camera so I know it can hear me. And the fact that it brings up an article on Selfies means it understands the word. It just no longer opening the camera correctly. What happened Apple?
