Once you share your location, both you and the person or people you’re sharing it with are able to see an estimate of how long it would take you to get to their location(s) by car.
If you want to share a static point on a map, and not your live location, you can still do that too – except, instead of choosing Share Live Location after you tap the location pin, just tap the red pin in the upper right hand corner. You’re then able to search for a place, or drag and drop the pin on the map before you hit Send.
Moreover, the feature is currently rolling out globally to all Messenger users on both iOS and Android. You can equally be checking out your respective app stores for an update.
