Can't Get Phone Link to Work

You are being sent through several sign-in methods, and repeated failed code matches can temporarily block Phone Link setup, explaining the “try again later” cycle. Stop retrying until the block clears, then update Phone Link on the PC and Link to Windows on the phone. Keep both devices nearby, on the same Wi-Fi, and begin pairing from the PC so it generates the QR code. On the phone, open Link to Windows, confirm that a QR code is visible, grant camera permission, and scan it. Link to Windows is built into some phones, so an Uninstall button may not exist; clearing its cache and reopening it is safer than removing system components. The Authenticator number is entered only when an approval prompt appears. If that prompt never appears, cancel and choose another sign-in method. After one attempt, record the exact error and contact Microsoft support if pairing remains blocked.
