Call it in and ask for a fix. In the Samsung you look for Pictures then go back and select Movies for that model to rebuild the cached info.
It's a mystery why there is no icon/button to do that.
Basically when I'm browsing my videos in Smart Share it's still listing 4 movies that have been deleted. When I try to play them I get the "invalid" error message so they definitely do not exist.
How do I get rid of these from showing up in Smart Share?
