It sounds like you’ve already tried the method u/hausman113 mentioned.
I’ve tried numerous methods to duplicate engagement and haven’t succeeded.
This post [https://www.reddit.com/r/PPC/comments/kqjcto/duplicating_ads_and_tracking_and_engagement/](https://www.reddit.com/r/PPC/comments/kqjcto/duplicating_ads_and_tracking_and_engagement/) from 12 days ago leads me to believe that it won’t allow you to copy engagement if there are multiple placement selected, multiple headlines, text options, etc, or perhaps something to do with UTM tracking.
If you figure it out please let us know!
