Can you tell me how I can completely uninstall and re-install the Netflix app? It seems that when I uninstall it simply removes it from my App selection, but does not remove the installation file. If I try to re-download I am sure it is simply re-installing
the original file, and not downloading a new one?

Is there a way to manually check for app updates?
