To modify an existing question, you’ll make a copy of it. Copying the question will allow you to edit the details, answer options, question content, etc. You can only copy questions you have authored.
To make a copy, click the 3-dot menu icon next to the desired question and then choose ‘Make a Copy’ from the options. Next, find your question under ‘My Questions’ and click the 3-dot menu icon and then ‘Edit.’
Editing the new copied question will be the same as editing a new question.
