I recently update my are on open street map
How much time it take to updated in game map
This is not a topic that wayfarer has influence over so I will close it.
The use of OSM to update the base map in the game is sporadic. It also takes appears to be that the data is downloaded and then it takes awhile before the update in the game.
So it is best to do the update to OSM and then you just have to wait, and hope that once the update happens your information has made the cutoff.
