Merchant Center notices do not all carry the same risk. Classify them as fix before release, observe, or non-blocking, then check the feed, GTIN, price, availability, and product status.
Verify your account, product data, and conversion signals, then choose Search, Shopping, or PMax and run your first controlled optimization cycle.

- Use Products, Needs attention, issue detail, and Data Sources processing to record the issue, affected item id, source, processing state, and last update time. UI labels may change;
