Windows 10 - Can't connect my magic mouse 2 via Bluetooth

Hi,

I called Genius Bar and no one could help me... :( I'm really sad I bought the Magic keyboard and mouse 2. My Keyboard was paired successfully via Bluetooth, but My mouse can't be detected by my computer in the bluetooth list.

So I made sure it was charged, plugged it in (as I did for the keyboard which worked fine), than my computer notified me the new device was connected, I see it as a new device, but once I want to connect it via bluetooth it doesn't appear in the list of device that can be paired.

Please someone help me I don't want to re-sell my new mouse :(
