My copy and paste from one apple device to another apple device is not working since I update my MacBook to macOS Monterey. Please help!

Hello Bing9723.

Thank you for using Apple Support Communities and for sharing these details with us. You mentioned that you're unable to use the Universal Clipboard feature since updating your macOS version. Universal Clipboard is a great feature to use. Allow us to assist in any way we can.

Are you able to use this feature between other devices? We want to confirm is this issue is only occurring when trying to use your Mac. If you confirm this issue is only occurring when trying to use Universal Clipboard with your Mac, we can suggest some basic troubleshooting steps you can try. First, try restarting your Mac to see if that helps:
