You can always email us at support@code.org with general feedback about any CodeAI content offerings, or bug reports! We typically reply within 24 hours on weekdays. 

For fastest service and less potential back-and-forth before a resolution, you can find our guide on how to best file bug reports, and provide important information up front that we may ask of you for our investigation, at https://support.code.org/hc/en-us/articles/360002531412-Filing-bug-reports.
