Every social media company/app wants us know to live by their notifications. This is why you shouldn't have any such app installed. I stopped using CNN and BBC apps almost immediately after I installed them on my 'then' smartphone on day1. I prefer the non-intrusive Firefox with its adblockers than the constant harassment of some random even that is not interesting and definitely not relevant to my life. LinkedIn is the meaning at useless unless looking for work, and even then 20mins in your PC will do just fine.
