Hello, I was wondering if someone could help me. Basically I accidentally changed my location from Europe to Africa as I was zooming in to make the map larger and hadn't realised the marker was on another continent (since I can't see the marker when the map is zoomed in). I purchased two credits to change it back but now I see that I'm unable to change my location again. Will I ever get another opportunity to do so or is everyone only given one location change per account? If the latter is the case, in the case where someone's made a mistake by accident, is it possible to change it back to the original location? Thanks.
