How can I receive Facebook Messenger notifications on my Apple Watch?

Meta (aka Facebook) removed their Messenger app from the Apple Watch App Store.

It is possible there is a 3rd party app that do what you want, but you would have to search for it, as most of us in this forum do not know.

Or you could contact Meta and request that they provide an updated Apple Watch app for Messenger.

In the Watch app, go to Notifications, scroll down to Messenger under Mirror iPhone Alerts From and make sure it's turned on.

It's handy for quickly checking and responding to messages without having to take out their phone every time. Although there isn't a standalone Messenger app for the Apple Watch, the notifications feature still allows for easy communication on the go.

As far as I know, you can only see the notifications on the Watch; you can't reply to them.

And what is answer to this question?

"How do I get notifications on my watch"

Can you tell me if someone uses Apple Watch to reply to messenger messages does it show them active on the the messenger app?

It seems like Messenger is not in the “mirror notifikations from iPhone” list

You can't, unless you DL a 3rd party app called WatchMessage... but it kind of seem a little fishy, since it asked you to enter your whole FB sign in information... so I did not DL it.
