Hello lauraofsuburbia,
We'd be happy to help. If iCloud says Syncing Paused, there are a few things you can try. To get started, make sure you're connected to the internet with Wi-Fi. Connect iPhone to the internet - Apple Support
This information may be helpful:
Connect iPhone to a Wi-Fi network
1. Go to Settings
> Wi-Fi, then turn on Wi-Fi.
2. Tap one of the following:
* A network: Enter the password, if required.
* Other: To join a hidden network, enter the name of the network, security type, and password.
If
appears at the top of the screen, iPhone is connected to a Wi-Fi network. (To verify this, open Safari to view a webpage.) iPhone reconnects when you return to the same location.
If you're connected to a Wi-Fi network, make sure you have Low Power Mode turned off. Low Power Mode will pause iCloud Photos. You can learn more here: Use Low Power Mode to save battery life on your iPhone or iPad - Apple Support
If syncing is still paused, leave your device connected to Wi-Fi, connect it to a charger, and make sure the screen is locked overnight. Syncing should continue when those conditions are met.
Thanks.
