it work with 4.2.0 but there is some lack of info how to configure it out... I can't find how to refund item - oh yes it's in market where link YES if item refundable - but there no option to set up item refundable or not in AdminPC.... there is no sign of Store items in profile either...
WHY developer didn't monetze that addon I do not know. He could be getting good money related to post count in this thread only for premium version if he sells it for around 20 bucks with premim features and support
Is this only addon to Experience? May be there more Market addons to it?
