I got through, it was quite slow as you've mentioned. Once the form goes through, you'll see a small message at the bottom that it was sent and all of the information provided will be cleared. :)
I just got it to work on desktop but the site is loading really slow at the moment, most likely due to the increase in traffic.
If you're on a phone, try switching to desktop mode. After you fill out and successfully submit the form, you will see a small message under the "Send" button that says "The form was sent successfully."
