Have you tried going back and forth in the form. Or starting over from scratch? (I know this isn't ideal, but I'm trying to get a better idea of what's going on for when I report it)
I have tried everything! I have like 5 hours tried! I have going back and forth in the form, change my email and nothing works. What is weird is that went I select corporation, my itch account email appears. ...But I'm not a corporation.
Alright, is it possible to share the email address you're entering? You can send it to support@itch.io (with a link to this topic so we know what it's for)
