Bests & Worsts Reviews from Amazon

If I get anything through Messenger, I have to open it online from my laptop. The app has not worked on my Fire tablet for over a year. I have tried downloading it several times, thinking "Maybe now it will work." Nope. I download the app, try to open it, and after a screen flash I am back to my home page. It does not matter if I open from the Appstore, Facebook, or my home page, the result is always the same: nothing.
