Assistant unable to do image search
I hardly ever make voice requests through Assistant, so I'm not sure when this problem started, but I am unable to make image searches.
I hold in my play/pause/mute button and ask 'images of cows', Assistant says (something to the effect of) 'Searching Google Images for cows', then it goes back to the main Assistant screen without opening a search.
Assistant does everything else as it should: non-image Google searches, sending messages, checking weather, etc.
It is not a feature that I am going to die without, but I hate that a feature that used to work, doesn't work anymore.
Anyone have any ideas?
EDIT: I have a Passport, if that makes a difference.
