I just made an edit to a question on an SE site. I wanted to strikeout some of the text, so I used the ~~ wrap to do this. I could see this correctly applied in the preview.
However, after posting the update, the rendered post just shows the original text with the ~~
, and not the strikethrough effect.
Example:
~~this text is strikethrough in the post preview~~
Screenshot from edit:
<del></del>
html tags to create strikethrough text. Looks like the tilde syntax was never supported but they may add it in the future
