Google Meet will ask for permission to use your camera and microphone the first time you launch the app. If you accidentally tap on Don't Allow, the app will not work correctly and you will need to change the permissions in Settings.
1. (K2 Only) Tap on the Info folder
2. Tap on Settings
3. Tap on Meet.
4. If the toggles next to Microphone or Camera are gray, tap on them so they turn green.
5. When both are green, it means that Google Meet has both microphone and camera access and they will work in the app.
