The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
This is a great app other than it needs a better admin area to see a record of the answers as well as what product page it comes from.
This can be out of control if you have over 100 products that need answering.
Be sure to keep track of all the question links or they will be lost. The email notifications are not 100% either.
Will give a 5 star if this changes...
