I tried creating an account on my computer and it got stuck with the same 401, i then tried it from my phone (not on wifi) and it got passed that but then when I had to enter the code that i was texted it said that my "Your account cannot be created at this time". I tried to just go create a new account and looked at the developer tools while I did it, got the same error but looking at the developer tools it sends back a 400 from the accounts api.......
Come on guys, this isn't that hard. You literally have people in this doing the debugging for you.
