Uploaded all my videos on both iPad and iPhone to my icloud...they each wouldnt show any videos uploaded from the other device (iPhone wouldnt show original iPad videos and vice verse). Saw the "clear cache" option which was supposed to help syncing issues....NOPE it cleared/removed all videos I had uploaded. GOOD THING I HADNT DELETED THE VIDEOS OFF MY DEVICES!! Wouldve lost some very memorable moments of my familys past couple years.
