Recently I was reviewing this post and I got result as failed.
What I observed as per this one post was:
The original poster provided instructions.
The original poster provided how to access the instructions.
Based on this above points I provided “no action needed”
Once I got the error I got the comment:
Welcome to Super User! This duplicates another answer and adds no new content. Please don't post an answer unless you actually have something new to contribute.
As the first post review, reviewer will view only one answer so for me there was no option to flag/identify it as duplicate.
Kindly let me know where/how I have failed the review test?
