I just tried this again in Edge Version 114.0.1823.58 (Official build) (64-bit) and it's working :smile:

Use the same procedure I explained in my post, it should work, just make sure Startup boost isn't on so that when you change the command line flags it will take effect immediately.

 

Cloudflare's website is also updated to support ECH and it detects it too.

 

 

Here i checked it with Wireshark too for this site: https://defo.ie/ech-check.php
