Stopped Working?

So out of nowhere I go to turn on my Tizen Tube app via my Samsung home screen this morning and for some unknown reason, despite me selecting it (numerous times) from the options (noting version 1.7.0) it no longer seems to working. The app shortcut in Tizen Brew still opens the YouTube app, but it's just stock YouTube, with all the ads as per standard?? Is there an issue with Tizen Tube or has some changed that I should be aware of? 15 minutes of having to put up with ads again and I'm ready to pull, what little hair I have left, out!!
