Lumia 520 user here n i just did the cyan update 2days ago, but i am frustrated that i can't find my videos which i downloaded using the youtube downloader free app after updating to cyan! I tried searching them under the downloaded files in the app but after tapping on it there's a pop up asking me to find the vids under "Video". But the only videos shown on my video hub r those vids transferred from my pc. Any idea where my videos disappeared to? 
Another problem after updating to cyan is that only a few of my favourite photos r shuffling on the start screen while other favourites r not shown, the photos only changes when I select "shuffle now" under settings, anyway to solve this?
