Although the idea of a single platform for managing reviews is valid and relatively well-structured, there are countless bugs and truly unacceptable errors (for example, when trying to import from Google, it suggests installing an extension to import Yelp!).
In my case, it was unable to import even the most popular reviews like Facebook and LinkedIn.

In my opinion, this is another case of software landing on AppSumo to acquire beta testers, not to provide value to the community.
I request a refund and thank those who produce honest and descriptive reviews that help others avoid situations like this.
