I've been having a problem with my Apple TV (3rd gen) recently. I wanted to mark an entire season of a TV show as watched, so I went into the episode listing, did the long-hold of the center button on the remote to bring up the "mark as watched" dialog. But when I attempt to select any of the options ("mark as watched" or "mark season as watched") nothing happens. The dialog just sits there and doesn't go away until I press the menu button, and nothing gets marked as watched. Anyone else have this problem? I have tried resetting my Apple TV (reset all settings, set up again from scratch) but this hasn't helped. I think this problem started manifesting itself after the most recent software update a few weeks ago. Unfortunately, there is no way to roll back an Apple TV software update, as far as I'm aware.
