Issue iframing page - "session expired" error

I’m attempting to iframe a url from bubble into squarespace, but continue to get an error message “session expired” when I interact with the iframe. I store all of the necessary data in the url so I’m not sure what the issue is, any thoughts…?

I figured it out! “Do not set cookies on new visitors by default” needs to be selected in settings-> general. If you are having iframe issues this is your solution!
