'''The main objective is to resolve legitimate map issues''' -- not just to close URs. Be sure to take time to understand the issue, and ensure that the reporter has time to respond. URs may be left open longer if needed to properly resolve the issue.
To improve your chances of getting helpful replies to your UR comments, use specific, personalized comments such as ''Last Tuesday at 5PM, Waze instructed you to turn right on High streetW 40th Street, but you continued straight on Market Street8th Avenue. What was wrong?.'' Avoid using generic generated comments, and be very cautious of any scripts which have options to automate your comments in any way.
It helps to let the reporter know they need to reply in the app, that email responses will not reach us.
