Hi @Katie,
Thank you for posting in this community.
I tested your question in my side. I found that edit button does not appear on the published page. Is it possible that the page you are modifying is published?
Before publication:
After publication:
We can't add an edit link or button to the published page because if the published page has an edit button or link, then the page content can be changed at any time and the point of publishing is lost.
Perhaps you can only modify the page layout by clicking the settings button and selecting the Edit Page button. Under the page area there has a page layout option.
