This has been happening for a while it’s actually from the company that supply the ATM’s so if you see an address it’s not necessarily wrong but if you feel to get it changed an in app chat might help it won’t update the map though just the location.
This happened to me at the weekend on a joint card where the ATM was showing Wales based and both myself and my wife were in England. Could not get hold of my wife so I froze my card in the app in a panic but it was a false alarm as it was bad ATM data.
SUGGESTION : Add some text visible in the app stating the ATM location data is not always 100% accurate. #Transparency
