Sorry folks, we don't have too much to go on here just yet, but we have received numerous tips from readers like yourself that the Official YouTube app from Microsoft is no longer available in the Marketplace in some areas. This seems to have started a few days ago.

This does not apply to the U.S. market but does apply to some in Europe (all?) and at least Singapore too. Could this have to do with Microsoft filing a complaint against Google via the European Union? If you recall, last March Microsoft's Brad Smith blogged about Google's unfair search practices and how they were restricting YouTube, resulting in a sub-par user experience on Windows Phone:

"Unfortunately, Google has refused to allow Microsoft’s new Windows Phones to access this YouTube metadata in the same way that Android phones and iPhones do. As a result, Microsoft’s YouTube “app” on Windows Phones is basically just a browser displaying YouTube’s mobile Web site, without the rich functionality offered on competing phones. Microsoft is ready to release a high quality YouTube app for Windows Phone. We just need permission to access YouTube in the way that other phones already do, permission Google has refused to provide."

Our bet? These two are definitely linked. We'll try to find out more, but in the meantime, lets do a roll-call in comments of countries affected. Austria? Check. Belgium?...

Thanks, Marcus H. and Borutes, for the heads up!
