Cannot see MC3 with Editor

I was able to connect with the updater and installed the latest firmware 3.8.3 I believe, but the online version of the editor will not recognize the MC3. It finds and works with my MC6 every time. I did a factory reset but no luck. It works and I can program it with the buttons but that is a pain.

Any recommendations?

Can you go to www.midimonitor.com and then click on devices on the website, and share a screenshot of the list of devices with your MC3 connected?
