With regards to reading aloud of text messages, there are a few things to look out for:
1. You need to be in Drive or Active mode.
2. Read my Inbox is for emails and does not read text messages. (Text messages are read aloud in real time when as they arrive.)
3. If you adjusted any messageLOUD settings we suggest you change those back and try again.
4. Please ensure that your text messaging app is set as your default one in your device Settings.
5. Make sure that your text message notifications are not turned off.
6. If you have any 'booster' type apps on your phone, these can block messageLOUD. Remove or disable these to test.
7. Please remove any other 'read aloud' apps, these will interfere too.
