Solutions
Solution 1: Enable Clipboard Sync on All Devices
- 1On EVERY device you want to sync:
- 2Settings → System → Clipboard
- 3Turn on "Clipboard history"
- 4Turn on "Sync across your devices"
- 5Choose: "Automatically sync text that I copy" (recommended)
- 6Or: "Never automatically sync text that I copy" (manual via Win+V)
- 7Verify same Microsoft account on all devices:
- 8Settings → Accounts → Your info — should show same account
- 9If different accounts: clipboard sync won't work between them
Solution 2: Fix Microsoft Account Sync
- 1Ensure account sync is not paused:
- 2Settings → Accounts → Windows backup
