I'm having trouble with the app – Spotify for Artists Review

I can't seem to claim my artist profile. I have to keep staring over and then it tries to have me link my twitter account and email. The end result is either one of two notifications, "something went wrong" or "sorry we couldn't find that page." I even tried using an alternate email. It's just not letting me claim my artist profile. I'm trying to get my blue check mark!
