The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
The app was great until it suddenly stopped working and disappeared from the store front. When I clicked on the app from my back end apps, a page opened up stating that "This site can't be reached". I tried it again and again, but same notice. I hope this is temporary, but in the meantime I'm looking for a replacement.
