Hi. Thanks for getting back.
I have just read through the guide but it doesn't quite answer my question.
I want to know how to make the video placeholder I created a while ago automatically appear on other similar post pages. Then I can assign a playlist of videos to that placeholder. Such that I don't have to manually create a placeholder for each post and video. I hope you understand.
Meanwhile, while I was checking the video ad tester, I discovered an error and an Ezoic guide recommends deactivating and reinstalling the chrome extension. Question: Will uninstalling the extension affect the existing ad placeholders on the site?
