Wont Sign In – Microsoft To Do Review

Won’t log in with my live account. I can with other apps but on this one it says “INTERNAL SERVER ERROR sorry, there’s an issue signing you in right now. Please try again and contact support if the problem persists. Error 401-JitBoxCreationfailed” I’ve tried looking it up on Microsoft’s support page but can’t find anything pertaining to that error code in this app, and of course I couldn’t imagine Microsoft would allow customer support for a free product.
