When expanding search campaigns to the Microsoft Audience Network, ad copy will be generated using approved search text ads.

This statement is True. When you extend your search campaigns to the Microsoft Audience Network, the system automatically uses your existing, approved search text ads to create audience ads. This streamlines the process, leveraging your current ad creatives for broader reach across the Microsoft Audience Network's various placements. This means you don't need to create new ad copy specifically for audience campaigns if you're expanding from search.
