When I click on the "Sign In" button, I receive a pop-up saying "Save purchases to a Microsoft account?" with two buttons, "Save to Microsoft Account" and "Leave on Device", referring to Marketplace purchases. If the first button is selected, a popup titles "Failed to login" and you're left with the original popup. If the second button is selected, the login failure popup appears and closes out the original popup. This issue leaves me unable to sign into my microsoft account, access my skins and other marketplace purchases that I have made at other times.
