Reviews and impact of negative review

Not looking to create a negative vibe, but just trying to understand how an app that has only 3 reviews, of which one of them is 1 Star, still has an overall 5 star rating? Can some one give a breakdown on the impact of negative star on the overall rating? Thanks.

Most likely a bug with the calculation. Should be escalated to Shopify team.

Not really fair on other apps, we sweat for every review, and we all know one Negative review pulls our ranking down. Hope someone from Shopify looks at this. Is it because it’s an app by a Platinum Partner?
