Connecting Bangle 2 Windows 10

Good question. So this all came about when I tried to update the latest firmware. If I try to pair via Chrome - its works and I then I politely tell windows I dont want to pair. I then try to go to the firmware uploader - select the firmware and after about 10-15 seconds - it stops. nada - no more uploading. It seems to disconnect. If I repeat again - same - same again - times out / stops uploading. Ok so this time - I do pair on Windows request and this time I can upload and it works. But next time I want to pair with Chrome - I dont see the Bangle until I remove the device from Windows and start again. So I can get it to work - but it seems like a faff...
