Magic Mouse 2 stopped working with Windows 10 via BootCamp

Hello,

I have a Late-2015 iMac 5k Retina with the latest macOS and Windows 10 Pro x64 thru BootCamp.

I have Windows set to automatic updates and I believe it may have led to the Magic Keyboard and Mouse 2 to be unusable. So I ended up using a secondary keyboard and mouse to use Windows. The Magic Keyboard and Mouse show up on the bluetooth list, but for some reason they're not responding when I try to use them. However, when I switch back into macOS, they work just fine, except for the mouse losing connection after EVERY time I reboot from Windows. Is this a common issue? Is there a fix? Work around? Any help is welcome. Thank you. 🙂
