The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
Unfortunately, there was no "zero stars" option to check. If so, that would have been my rating and I am an easy grader.
I tried writing this app company 3 times and never received a reply.
Terrible experience. Do not recommend.
Crap support... the app is a good idea, but the support makes it hard for it to work on your website... its a shame.
