Mass Historical Reviews Disappear from Mercado Libre Product Pages; Sellers Confirm System Bug as Likely Cause

On September 21, it was reported that a large number of historical product reviews have recently vanished from public-facing pages on Mercado Libre, leaving only a small number of new reviews visible for some products that had accumulated long-standing genuine customer feedback.

Sellers have verified that in most cases, the missing reviews were not removed as a penalty for fake review manipulation. Instead, the issue is a systemic bug that coincided with the timeline of Mercado Libre's recent large-scale backend system update. Some sellers managed to recover their missing reviews after reaching out to local platform account managers for assistance or submitting support tickets, while other cases returned to normal automatically after a period of time. Misaligned attribute tags on older product listings, which caused abnormal review synchronization, is considered one of the possible triggers of the glitch.

In terms of impact scope, older listings with slow sales velocity saw limited impact, but core high-performing listings that rely on word-of-mouth for conversion recorded a notable drop in conversion rates.

Sellers are advised to first audit the review missing status of their core revenue-driving listings, then contact local account managers for follow-up and submit support tickets for appeal, pending full system synchronization recovery.
