Having problems on-boarding? Post here!

I get that this is meant to pertain to the developer onboarding vs. the affiliate onboarding, but there has been much discussion related to the latter, so here goes:

My process has been stuck “under review” for nearly three weeks. Many streamers, and the Twitch website itself, have told me they went through the entire process in a few minutes. Support told me I likely need to “start over”, which I’m supposedly able to select from the onboarding main menu. Turns out that no such option exists for me. At their request, I provided screenshots showing that this was the case (see below); but, they are now dismissing me with claims that they can’t interpret the tax forms for me, which I have never asked them to do at any point. All I want is to be able to “start over”, per their recommendation.

This thread is riddled with others who have one through similar experiences, but I can see they are able to get subscribers, meaning they had their issues resolved. Sadly, no one comes back to talk about the steps that led to their resolution, which would be most helpful for the rest of us. Can anyone provide some details as to how they finally got to onboard? Thank you.

(If it matters, my Twitch username is the same as here.)
