Microphone does not work in messenger app

Hi What_the_heck49,

Thank you for using the Apple Support Communities! We would recommend the steps below if an app isn't working as expected:

If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open

1. Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2. Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3. Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4. Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

Hope this helps!

Have a great day.
