try wiping cache and data for messenger, uninstalling the app, and then re-installing it. if that does not work, then most likely the app has not been updated to work with the update on your phone. you can contact the developer and let them know or just wait until the app gets updated.

 

long push the app in the app drawer, drag to home page.

 

not sure how that will help the op as that just adds the app to the home screen. it does not help the op get a popup message of a new text. plus this thread was started last year.....no reply from the op, so hopefully the issue got fixed.

 

messenger or messages....my comment was to replace what i thought was fb messenger app.

fwiw: i use verizon message+ , from within the app select pop-up + will verbalize the message! not sure if same capabilities are available with other messaging apps.
