Assuming that I’m going to buy something from Epic’s Marketplace, hypothetically, I should give positive review of course, as I should trust in the quality control and by staying so long time in Trello … But, before to enjoying any Cool 4-Free Negative Review, I should to contact the author before. If our quality control in the marketplace does not fail, hypothetically, many of us, yes, we can fail, sometimes lack experience and poorly programming knowledge or any misunderstanding.
If I want to give some feedback, Then so be a positive review/feedback, in the direction of improvement. Or no review: I was indifferent. Or negative: It did not meet my expectations, I was mistaken, was poorly documented, I did not make it to work, Where did I go wrong? I Need Help! - If the author no longer corresponds to the quality standards imposed by Epic, does not offer security or assistance to marketplace customers, is simple, Epic should intervene notifying or even deleting our hypothetical slippery author.
But as qdelpeche said a few posts above, this is a “double-edged sword” …
Lastly, I still want more rely on the Epic’s marketplace than Sellfy.
