Magic Mouse 2, windows 10, boot camp

I installed Windows 10 enterprise on my new iMac Pro using bootcamp, but Magic Mouse 2 and magic keyboard could not work in Windows. They were connected but could not be used. If I restart and switch to Mac OS, they will work just fine.

In Windows the only way I could use them was to remove them from bluetooth and re-connect them. And I am having to re-do this every time when I switch to windows from Mac.

I can use USB keyboard and mouse, but I still wonder how could this problem be fixed.
