Walgreens Activity Monitor Advanced

I'm usin a fusion lite. When I first started it up, it was receiving notifications from text and Facebook messenger....but now it only works for phone calls. When I go into the app to change the settings, it only shows an option to turn on/off phone notifications. Why is that? How do I get text notifications to come back. I've tried resetting, factory reset, de-registering, deleting the app, etc.
