Yesterday I received notification that MIUI 13.0.3 was available for my Poco F3. Since downloading it, Google Assistant " Ok Google" no longer works automatically anymore, whether on screen lock or whilst the phone is unlocked. When you say "OK Google " a green microphone appears in the top left hand corner of the screen and when you tap, all it does is to say " Being used by Google". What has changed ? I've tried closing the app, turning on and off the phone but nothing works since the new update.
