Welcome Rafu,
Thanks for reaching out to Microsoft Q&A Forum. I understand you are unable to send content from your phone to your Windows 11 PC using Link to Windows.
Please make sure you already tried the Q&A Assist steps. In addition, please try the following.
1, If you are using an Android phone:
- Open Phone Link on your PC and confirm that your phone appears as connected.
- If you are trying to send a file or photo, select the item on your phone, select Share, then check whether Link to Windows – Send to PC appears and whether your connected PC is listed.
- Check for updates for both Phone Link on the PC and Link to Windows on the phone.
2, If you are using an iPhone:
- Open Phone Link on your PC and check whether the iPhone is still connected.
- Make sure Bluetooth is enabled on both the iPhone and PC.
- On the iPhone, open Settings, select Bluetooth, select the information button next to your PC, and check the available synchronization permissions.
3, Restart both the phone and PC, then open Phone Link again and check whether the connection is restored.
Looking forward to your update.
