I had to reopen it because it shows "build Expected - Waiting for status to be reported". And the online references suggested to close and reopen.
This still doesn't work. Can you let me know where it might be going wrong? Thanks! 😄

It is a documentation change. Perhaps that is why no "build" is required.
