Just a bit of further information. Yesterday, I cross posted this blog post:
https://fiddlingforolderfolks.com/learning-a-fiddle-tune-by-ear/
in this forum section: https://fiddlingforolderfolks.com/community/exercises-practice/
It appeared with all the comments.
Today, I decided to move it to a different section of the forum, so I deleted it and re-cross posted it to this forum section: https://fiddlingforolderfolks.com/community/education-learning/
It cross posted, but again without cross posting the comments, just like the Trigger Finger Post I made yesterday when I moved it.
Thought this might be useful to you in trouble shooting.
ADDED: Also it did not appear in the "Recent Forum Posts" widget on the home page.
