If your files still are not showing up on one or multiple devices after completing the steps under 'General Setup', continue with these steps to ensure syncing between devices works as expected.
First, go to iCloud.com and check if the files are appearing there and have the latest changes in them. If the files are available on iCloud.com, continue the following steps on the device that is not getting the updates, if the files are not available on iCloud.com, continue the following steps on the device that added the file to iCloud Drive or last modified it.
Turn iCloud Drive off and on again in the device's settings. You probably only have to do that on the device that is not receiving updates, but doing it on all your devices is a safer bet.
Restart the device. This restarts the processes in the background that are responsible for updating iCloud Drive.

- macOS: > Restart...
Check the Apple System Status page and check if 'iCloud Drive' is available.

- iOS: Go to Settings > General > Date & Time. Make sure 'Set Automatically' is turned on.
- macOS: Go to > System Preferences > Date & Time. In the Date & Time tab make sure 'Set date and time automatically' is enabled.
Make sure you are not behind a firewall that blocks incoming or outgoing traffic to iCloud. On macOS, if you are using tools like Little Snitch, TCPBlock, or other network tools, disable them or make sure they are configured properly.
Sometimes it takes up to 72 hours for iCloud to propagate new files or folders.
