Just bought the new fire tv stick, it's setup and I am enjoying content from a multitude of apps. But IMDB tv app does not play sound during a program. It's not hardware because there is sound during the initial (5-second) IMDB tv branding and again during adverts. It must be app related, so I wanted to uninstall and reinstall it. I cannot though because the app doesn't show up in the "manage installed apps" list in fire tv's settings menu. Any ideas?
