Hmm, where do you see this? I don't use Messenger, but many of my friends do, and I've never seen this. Is it only for Messenger-to-Messenger chats?

I couldn't get a screenshot with the map popped-up, but if you go to "see all" on the web, you can get a full-screen view with these little location pins. Hovering over them gives you a map.

Ah, thank you, these weren't in the small chat windows. Clicking on them gives you a full, browsable map, as well.
