Now you can give the customer support experts in your organization the ability to respond to customer reviews on the App Store with the new Customer Support role in iTunes Connect. Users with the Admin or Customer Support role have the ability to respond to customer reviews.Apple began allowing developers to respond to customer reviews with iOS 10.3 and macOS Sierra 10.12.4, a feature developers had long requested. The ability to respond to customer reviews allows developers to address negative reviews and offer better service to App Store users.
Your team's admins may choose to assign only this role to users, or assign this role in combination with other roles. Users who have been assigned only the Customer Support role can access Resources and Help, Users and Roles, and My apps in iTunes Connect. When they click on an app in My Apps, they'll go straight to Ratings and Reviews where they can respond to customer reviews.
Prior to iOS 10.3 and macOS Sierra 10.12.4, developers had no way to respond to issues that customers reported via an app review, so there was no way to mitigate a negative review or further converse with a customer having difficulties.
