A note on Creating New Ads
You will not see the option to Duplicate or create new ads if there is a Dynamic Creative ad in the ad set. Dynamic creative ads create lots of ad versions b mixing and matching your text combinations. Facebook does not allow you to create more ads alongside the mix and match ads.
I you want to write specific texts to go with specific images you will need to create these ads one by one.
A note on DELETING
Old ads and ad sets collect data, and if you delete them from your dashboard you lose the ability to view that data and gain insight into your past campaigns.
The data from past campaigns provide you with valuable insight you can use to guide your current and future strategies.
