I'm trying to submit an app. I archived it and then tried to submit it and upon so, it crashes. I looked up potential fixes to this problem and they said just go to preferences > accounts > and update to make sure you've agreed to all new terms. So I did that and tried it again and now it's still crashing. I haven't found any other solutions.
Edit: I went through the itunes connect instead and I think that should work, but I'm still curious as to why there's an error.
