I'm running Windows 10 Pro and am trying to encrypt an external hard drive using BitLocker. I can see the BitLocker option under the Drive Tools tab in File Explorer, but when I select "Turn On BitLocker" I get the following pop-up message:

I also enabled the Control use of BitLocker on removable drives with the Local Group Policy Editor (but I don't think that should matter given what the documentation says since it wasn't configured previously).
What am I doing wrong?
