Amazon blocked Meta's Muse shopping agent from Amazon.com and asked Meta to remove the retailer from the service, saying the agent did not identify itself and appeared to capture and store customer credentials. Meta has said Muse cannot see passwords or payment methods because user-supplied information is held in secure storage.

Amazon also amended its federal complaint against Perplexity, alleging that Comet for iOS copied Amazon session cookies to Perplexity servers and accessed the retailer through a cloud browser. Perplexity has not responded to the amended complaint; its assistant feature on Amazon was temporarily disabled in May.
