The Help Portal Contact Us page does not allow Twitch users to report actual software issues with the website.

For example, I have encountered a bug on the main website Twitch.tv homepage. There are no options in the Help Portal that allow me to submit this bug report. The relevant options either lead me away to separate web pages when I try to fill in the form and select categories, or the sub-categories simply DO NOT EXIST.

This is baffling. How am I supposed to submit a bug report?
