Notifications are not showing for text messages in my app at all, the only way I know that I have a message is by going into the app and checking.
I have tried to turn on notifications in settings but that option has been greyed out. Is there anything else I can do to get notifications to show?
the grayed out 'Show notification' does not mean its turned off. it means you cant turn off the notification.
when you click on new messages, is it on Alert or silence?
if its on Alert, click on sound and check if if its on sound or Slient.
