Facebook Messenger

Something is drastically wrong with Facebook Messenger. When I deleted several conversations the system deleted all my Messenger people. One person I can get back by going to the App Store & clicking on Facebook then clicking on the Messenger symbol & she comes back but only her—-the rest are still missing. When I click the search bar 20 people reappear in my Messenger list but Kathy Yungwirth who I just got added by going through what I mentioned above disappears again. When I get her re-added the other 20 disappear again. What in the world is wrong? I use Messenger regularly because then my messages go only to that person I am writing to & not all over when I only want the 1 person to see it. If I find more that will help you with the issue I’ll write another review.
