Why social media apps not working on ios 10 and less?

This is the reply i got from apple team

""Your iPhone apps won't open because your iPhone has a software problem. When an app crashes, it usually doesn't take the whole iPhone with it. ... In my experience, iPhone apps usually won't open because of a problem with the iPhone operating system (iOS), not a problem with the app itself.""

All the social media apps are not working including"" facebook instagram speed test twitter tinder"" and many more
