What is Brands Notifications and how does it work?

Brands Notifications (also known as AZAlert) is a feature that identifies brands that have been known to file various types of claims against Amazon sellers both selling under FBA or FBM. 

The brand notifications tooltip is triggered if the ASIN you are viewing is owned by a brand that one or more Amazon sellers reported receiving a claim against.
