Not only am I unable to update it to the latest version, but now the app won't even let me log into my account. This is the only Google app with this malfuntion. Now I either need to use the browser version or just live without being able to use all the features (subscribe, comment, etc.). Also, whenever I close the app, I need to 'update' it again. Meaning: uninstall, update, open. Close and repeat. What a waste of time Youtube has become.
