Google seems determined to make Microsoft’s life miserable when it comes to approving a YouTube app for the Windows Phone store. The Verge reports that Google has once again blocked Microsoft’s Windows Phone YouTube app because it still allegedly violates Google’s terms of service. Google first blocked the app three months ago when it said that Microsoft created it without Google’s permission and added features to the app that prevented ads from playing on YouTube videos. The two companies have since vowed to work together to make an app for Microsoft’s mobile platform but this latest dustup shows that the two companies are still far apart. Microsoft tells The Verge that it is working with Google “to resolve the issue.”
