If you are launching and testing as many campaigns, ad sets/ads as me it's very convenient to use.
You can duplicate ads/ad sets into multiple campaigns at once.
I know it might not seem like that big of a deal, but that extra time definitely adds up.
So, it's nice to be able to do things a little more efficiently now.
You just select whatever you want to duplicate and press command and C.
Then select where you want it to be duplicated and press command and V.
A much quicker process now.
Highly recommend it!
