How do I unpause my iCloud download?

Hello sari177,

Thank you for using Apple Support Communities! I understand that you need help with unpausing an iCloud download. I am happy to help the best I can.

When you turn on iCloud Photos, the time it takes for your photos and videos to upload to iCloud depends on the size of your collection and your Internet speed. If you have a large collection of photos and videos, your upload might take more time than usual. You can see the status and pause the upload for one day.

• On your iPhone, iPad, or iPod touch, go to Settings > [your name] > iCloud > Photos. You can also open the Photos app, go to the Photos tab, and scroll to the bottom of your screen.

Check out the following support article, which provides some steps to try for this behavior: iCloud photo library upload paused - will… - Apple Community
