Hey @wkarberg, it should appear in Windows Explorer if you select either “Transfer Files” or “Transfer Photos”.
There are a few things I’d check (after you make sure everything is updated and you’ve restarted your devices of course):
Ensure the cables you’re using can be used for data transfer for other devices
Ensure the USB port on your computer is clean and supports USB 3.0 speeds
Try a different computer and ensure that the same issues occurs there
Lume Pad should already be working in your situation so if the above troubleshooting steps don’t work, reach out to help@leiainc.com and we can replace your Lume Pad if there’s a defect.
