Hello!! I wasn't able to find a feedback form anywhere so I'm hoping this could reach the team that made the submission form for the challenge. I was really hoping the form could save our progress. Working on the longer response questions does take time, and it's incredibly frustrating when the site tends to reload, losing all progress and causing me to copy everything over again.
Feedback for the submission form
Thanks for the post, I would recommend you to send an enhancement request for that form.
If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.
If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?
Cheers,
Albert Pascual Worldwide Developer Relations.
