According to a Forbes report, earlier this week, Microsoft released its new YouTube application for Windows Phone after it was disabled in May 2013 by YouTube for failing to display ads. Though the new app displays ads, the app was blocked again by Google, apparently because the app violates YouTube’s terms of service, even though the two companies collaborated on the app, added the report.

Forbes reported that in a statement, Google said: “We’re committed to providing users and creators with a great and consistent YouTube experience across devices, and we’ve been working with Microsoft to build a fully featured YouTube for Windows Phone app, based on HTML5. Unfortunately, Microsoft has not made the browser upgrades necessary to enable a fully-featured YouTube experience, and has instead re-released a YouTube app that violates our Terms of Service. It has been disabled. We value our broad developer community and therefore ask everyone to adhere to the same guidelines.”

Microsoft’s Corporate Vice President & Deputy General Counsel David Howard responded with a blog post that alleges that Google is now making up reasons to block the app, added the report. “It seems to us that Google’s reasons for blocking our app are manufactured so that we can’t give our users the same experience Android and iPhone users are getting. The roadblocks Google has set up are impossible to overcome, and they know it.”
