both my iPhone and homepod mini suddenly have stopped taking commands to play music via siri. If you ask you get "there is a problem". I cam request other things like turning lights on. Also, my iPad still works fine. To be more specific, if i ask for 'classical music' it plays, if i specify an artist or song it does not. I have managed to fix the homepod by resetting it - a quick job. I guess a restore on the phone is on the cards but don't really want to have to do that! Any thoughts?
