For unmoderated tests, you are able to edit the Task Text and the Tester Greeting. You are not able to edit any of the links after the study is launched.
All studies provide a Preview URL that you can use to test your study before launching it. The preview test will run exactly as a launched study but the session will not be recorded.
You can also duplicate a launched study and edit the newly created study.
