Syncing

Hi GHAR,

Thanks for reaching out to Apple Support Communities. It sounds like you're having an issue with syncing iCloud. We're happy to provide some information to assist.

If this is on an iOS device or Mac we'd recommend ensuring your Wi-Fi connection is strong.

Connect to Wi-Fi on your iPhone, iPad, or iPod touch

Manage the Wi-Fi connection on your Mac

If the issue continues, check out and complete the steps here: If you can't connect or sign in to iCloud

If this is only related to the upload of iCloud Photos on an iOS device the section below from the article here may help: Set up and use iCloud Photos

"Pause library uploads to iCloud

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, open the Photos app, go to the Library tab, and tap All Photos. Then scroll to the bottom of your screen.
• On your Mac, open the Photos app. Select Library in the sidebar, then click All Photos in the list of tabs in the toolbar. Scroll to the bottom of your photos and click Pause."

If the issue continues, provide a bit more detail about the device and which iCloud feature is attempting to sync. We'll be happy to continue to assist.

Best!
