Otherwise Samsung won't know it failed and will delay a fix for others.
Only Samsung can fix Samsung Apps. Since the YouTube app is by Google, when Google changes, you see issues like this. It's becoming a sad statement about what these makers were planning for long term support.

This started randomly one day last weekend. I have a Samsung Smart TV Blu-ray player and the menu has a YouTube app on it. It used to work perfectly fine, but now whenever I open it, a message pops up saying: "The webpage is not available. The webpage at http://www.youtube.com/tv?launch=menu&additionalDataUrl=http://localhost:56789/dialData?app=YouTube might be temporarily down or it may have moved permanently to a new web address." I know it has nothing to do with my internet connection because all my other apps work fine, and my software is also fully up to date. How do I fix this?
