The overall rating reflects the current state of the app. It accounts for all app reviews but prioritizes the most recent ones.
The support is pathetic. Have been chasing them for days for a simple integration which the app claims its done in 60 mins. The trial period says 7 days and then gets expired in 2 days. Not recommended at all.
This app never worked. Asked for support, never got an answer. Would not recommend this app or this developer.
