Have you tried messenger.com from your browser?
Edit:
Just went on it. On a browser you have to enable desktop mode for login to show.
Also if you login this way and disable desktop mode it forces you out. If you reenable it renders the chat. Theres no reason the chat wouldnt work on Mobile desktop mode isnt using a different browser just lying to the web server and frontend JS.
Amazing. I already rarely use Facebook as it is. I might just outright stop since they are dying to infest your phone so badly.
I actually believe part of it is that they rely on this editor[1] for the messenger and anyone who tries to use it on any device that supports IME (like phones) will find that it does not work at all.

That's a library made by Facebook though... How odd, I doubt they don't have the resources to fix that problem in their own library.
Not so much that it doesn't work at all. More like, it appears to work and then fails horribly down the road.
I've been bitten by it too much. It's typically the auto-complete feature of mobile keyboards that fails. Something that you don't always see in emulators.
This. This is what regulators should be concerned about.
