Why is audio recording not working?

iOS now asks for permission to use the microphone with any app that requests it. Mental Case needs the microphone, so you should see a request the first time you try to record audio. If you absent-mindedly deny the request, audio recording in Mental Case will not work.

To fix this, go into the Settings app, and then into the section Privacy > Microphone. Make sure the switch for Mental Case is turned on.
