As of today, the chime after saying "hey google" has stopped working. When locked or unlicjed, it used to launch Gemini and chime, waiting for the command etc. Now no longer. If I say this when waze is running though, the google assistant will pop up and chime as normal, but if my phone is sitting (locked or unlocked), gemini launches but without the audible confirmation it's listening. Does anyone know hiw to fix this? No accessibility settings seems relevant and I've not made any system changes to cause this. Thanks
