Hi! Could you please clarify the reason for changing the maximum speed limit from 40 to 30 on this road? 
According to the latest OSM sources (Mapillary traffic signs overlay by 2023), the maximum speed limit is 60 here (24.4729604, 54.31981529).
In your comment you do not specify what other evidence you use for making such changes. Would you mind giving more context of your edit? We want to make sure it’s aligned with the OSM editing guidelines. 
Best, Marina.
