Yes, many sellers have experienced the same situation where Amazon keeps responding with “we’re reviewing your case” even after submitting all required documents like invoices and a Letter of Authorization (LOA). This kind of delay is unfortunately common, especially with brand-related or inauthentic item appeals. Sometimes Amazon’s internal teams take longer if they need to verify the supplier or brand contact, or if the case is under review by multiple departments. Resolution can take anywhere from a few days to several weeks depending on the complexity and how responsive your supplier is if Amazon attempts to contact them. In the meantime, avoid sending repeated messages, as it can push your case to the back of the queue. If it’s been more than 7 business days without a meaningful update, you can politely follow up once, referencing the case ID and asking for a timeline. If nothing progresses after 2–3 weeks, consider escalating via Seller Performance Escalation or Executive Seller Relations (e.g., [email protected]), especially if your inventory or account status is being harmed by the delay.
