Xbox One SmartGlass apps for Windows Phone are currently crashing on startup

It looks like the start of 2015 isn't going so well for Microsoft's Xbox One SmartGlass apps for Windows Phone. Both the regular and beta versions of the app, which is used to help control the Xbox One game console, are currently crashing for many users on startup.

We started receiving tips about these crashes earlier this morning, and our own tests of the Xbox SmartGlass apps confirmed that they will not work when launched on our own Windows Phone devices. It's possible this issue is date related, since it started happening close to the time of the changeover from 2014 to 2015. We will update this post when Microsoft updates these apps to fix this problem.

Update: It looks like this same problem is happening to the Xbox One SmartGlass app for Windows 8.1 as well.
