The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
App is a bit of an interesting piece to work with. setting up the rules is fun, but the end result was for me not impressive. Was unable to successfully connect to Amazon API. The feeds also linking my Google /Bing Ads accounts were not synchronizing with the merchant accounts properly. it was a bit of a headache. and then the bills were coming. Summary, It did not work for me, maybe it would for you the reader. I have found a more seamless approach.
