From the users list we can read when a user is offline. And we can also check its profile picture border color or the color of its marker on the map. When green, that user is online, orange offline and gray when either of us don't want to share our location. This fact is shared with it in the same way that we see when it has muted us.

Both when we mute a user or when a user mutes us we see that profile with a gray border. In the video below we can also see how a user (the one on the right) has muted the other (the user on the left) so this can not see either when it is offline (a muted user will always see that the other is offline)
