When using Edge Dev Beta in a work environment, if a computer is Azure AD Joined and has Conditional Access policies in place, Edge Dev Beta does not seem to register with the CA system and results in a "not compliant Browser" within the CA system.
I too have this issue. We just started enabling conditional access for managed devices and laptops. It works great in Chrome with the Chrome extension "Windows 7 Accounts". So I added the extension to Edge. It logs me in without prompts but still prevents me from actions based on the CA rules.
