Hi Jessy,
I'm Sumit, here to answer your query at the Microsoft Community.
Are you sure both devices have the same OS?

You can choose to have your copied items sync automatically to your other devices.
Note: The sync feature is tied to your Microsoft account or your work account, so remember to use the same login information on all your devices.
Select Start > Settings > System > Clipboard .
In the Sync across your devices section, set the toggle to On.
Select Automatically sync text that I copy.
Note: The Manually sync text that I copy option would mean you'd need to open your clipboard history (Windows logo key + V) and manually select the sync button on the clipboard item. Then the text would be uploaded to the cloud and synced to other devices.
Hope that helps, and rely on us for any further inquiries. All the best.
