SMS Conversations disappearing in FB Messenger

[Android Central Question]

I've been using FB Messenger for text and Facebook chat for years now and for whatever reason I can send SMS through the app. The conversation will appear in my app for a few minutes usually around 10 or so. Once I open the app up again to reply to the conversation it will be gone and I will have to open stock messenger app to reply or search the contact in the app and reply that way. Has anyone had this issue? Anyone know a fix? I have an Honor View 10 on AT&T's network.

Anyone know a fix?

For something written by Facebook? Always suspect Facebook as the cause. Email them to complain. (The site works. The apps? Meh. Sometimes they care, sometimes they don't.)
