Some Xbox Live users are experiencing difficulty purchasing content and game subscriptions for the Xbox One, according to the official Xbox Live status page.
"Our engineers are working diligently to get everything back on the up-and-up as quickly as possible," the page reads.
Xbox Live's other services appear to be functioning as normal. Further updates are expected shortly.
We've contacted Microsoft for more information and will update accordingly.
Update: Services appear to be running normally again.
