Preview url editing not working

What are you trying to accomplish
Typically we use feature branches to QA new features. We have QA testers edit the preview url on pages to test editing experience changes. Today we have found that editing the preview url does not work, it still continues to show the main QA page. If you edit the preview url using developer options, the feature branch changes are visible. Our QA testers do not have developer permissions so this will not work for testing.

this issue is not limited to this feature branch or page

Please let me know if you need any additional info!
