Hi, I'm John! I will help you with this.
I understand what you mean, it sounds like you’re getting sign-in prompts when trying to comment or interact on certain pages. Just to confirm, are you referring to MSN news articles where Edge asks you to sign in before posting a comment?
If that’s the case, those sign-in requests are required since comments on MSN are linked to Microsoft accounts for moderation and safety reasons. But if you’d rather just browse freely without signing in, you can click your profile icon at the top-right of Edge and select “Browse as guest” from the “Other profiles” menu.
Any additional info about the issue you can provide will be helpful in diagnosing and resolving the issue.
