Map Update
Which map layer are you talking about? If OSM, you should probably just fix the issue yourself because OSM is made by user contributions.
If you want an OSM edition you just have to go to www.openstreetmap.org click with the right button on the area that has an error and select "add a note here". This will allow an OSM editor to make changes.
Dear Traccar Team,
I trust this finds you well. I've Just noticed that the Map being used by the App is not updated. kindly review this. I believe Google Map and Open Street team would be happy to contribute to this...
