Google has blocked Microsoft’s recently released YouTube app for Windows Phone for violating terms of service.
According to The Verge, Google stated that Microsoft did not make the necessary browser upgrades to enable a fully-featured YouTube app.
The app was released earlier this week. It had been working well on Windows Phone devices before errors started to appear.
The errors began appearing after Google revoked an API key that Microsoft had been using.
The news comes as a surprise, since Microsoft and YouTube had been collaborating on building a YouTube app based on HTML5.
It is understood both companies are working to resolve the problem.
