I've had quite a lot of weirdness with my PageFlip Firefly on Windows 10 Surface. I can't find it in bluetooth settings, it shows up as "unknown device" and then when I finally give up I notice that it's in device manager all installed and ready to go. I've been through this several times.
Anyhow, to say something useful: Mine has the usb jack and I generally have it sitting in my office beneath my music stand, so I've plugged it in to power and since then it hasn't "unpaired" once. So if this is an option for you, try running it on line power instead of batteries.
(I know it's not the same model, but it's close! And both have a USB power jack.)
