Cross-device clipboard not working on Windows 11 25H2 (Phone Link connected, sync enabled)

Hi everyone,

I’m experiencing an issue with cross-device clipboard sync between my Windows 11 laptop (Version 25H2, Build 26200.7840) and a Samsung S25 Ultra.

What is already working:
Phone Link shows the phone as connected, Bluetooth pairing is successful, Clipboard history is enabled in Windows, Sync across devices is turned on with automatic sync selected, the option to allow this PC to access mobile devices is enabled under
Settings → Bluetooth & devices → Mobile devices, the phone is signed in using the same Microsoft account, and cross-device copy and paste is enabled in Link to Windows on the phone.

The problem:
Even with all required settings enabled, the phone does not appear under Mobile devices, copy and paste between the phone and PC does not work, and no errors are shown in Phone Link or Windows settings.

Additional observations:
The system is running Windows 11 25H2 (Build 26200+). Some legacy sync services used in older builds are no longer present. This appears to be a device registration or cross-device platform issue rather than a configuration mistake.

Troubleshooting already attempted:
Re-linking Phone Link from scratch, signing out and back into the Microsoft account on both devices, clearing Link to Windows app data on Android, restarting related Windows services and rebooting both devices, verifying clipboard sync settings multiple times, and installing the latest Windows updates available for this build.
None of these steps resolved the issue.

Question:
Is this a known issue with Windows 11 25H2 / Build 26200+ that affects cross-device clipboard registration?

If anyone has a confirmed fix, registry or feature-flag workaround, or official confirmation from Microsoft, I would really appreciate the guidance. This could also help others using newer Windows builds.

Thanks in advance.
