# Why does Markdown not always work?

In this post, I selected text and marked it bold with two stars. But it displays for me (both in preview and after posting) like this:

Is this related to the move to CommonMark as noted in the post, Why don't images show up in a post?. Is there something I need to update in my browser (MacOS/Chrome) to get Markdown working as it used to?

It's best to use only HTML or only Markdown within a single paragraph in your posts. Replacing **Added 4Aug2020** by <b>Added 4Aug2020</b> should do the trick, and adding a break between <hr /> and **Added 4Aug2020**. works too.
