to enable the iPad microphone for message from me
Go to your iPad settings and click on the "Privacy" tab on the lefthand side of the settings.
On the right, you will see a list of requests. "Microphone" should be on this list. Click on it.
On the right, you will see a list of applications that have requested access to the Microphone. "Msg from Me" should appear on this list.
Check to make sure that the button next to "Msg from Me" has been switched to the ON position (in order for the app to work, this button should be green, as it appears below).
