DoH on (Chr)Edge

Has anyone gotten DNS over https working with Edge? I have enabled the flag #dns-over-https, but when I check at 1.1.1.1[/]help, it shows that I am not using DNS over HTTPS. When I check with Firefox, I get a “Yes”.

My FiOS router is set to use 1.1.1.1 for DNS lookup.

Any other setting that I might need to check?
