How to create Sponsored Display and Video campaigns?

You must have a brand enrolled to Brand registry for at least 2 weeks.

If you already have an enrolled brand, but still don’t see the activation checkboxes, then you need to submit an Ads Console support ticket at https://advertising.amazon.com/contactus with the following message:

I’m a seller with a registered brand in Brand Registry; however, I don’t have access to the store builder or access to my brand. Could you please help correct my brand configuration so that I can get access to store builder?

The support team in the Ads Console will resolve this issue and the process will take within 2 weeks or less. This is an Amazon-side bug and can happen on some accounts even if they had previously activated display or video campaigns.
