Videos not playing

Hi Fatemeh_fatemeh,

Thank you for using the Apple Support Communities! As noted in the article below:

Set up and use iCloud Photos

iCloud Photos keeps all your photos and videos in their original, high-resolution version. To save storage space on your device, you can turn on Optimize Storage.

If you turn on Optimize Storage, iCloud Photos automatically manages the size of your library on your device. Your original photos and videos are stored in iCloud and space-saving versions are kept on your device. Your library is optimized only when you need space, starting with the photos and videos you access least. You can download the original photos and videos over Wi-Fi or cellular when you need them.

Hope this helps!

Have a great day.

Hi Lizzy,

Can you please elaborate on this more? This is not the same thing as Optimizing Storage. There is no option to download and I am unable to watch ANY of my videos - Zero.
