I am having issues with this new markdown changes. I used to be able to switch to heading 3 by typing h3., but that does not work any more. The documentation here says to put ### around the text, but it does not seem to work. I tried ###<text>###, ###<text> and it was not changing to h3. After several trials, I accidentally put a space after the first ###, (i.e. ### <text>) it switched to h3. I think it would be good to add that minor but important details in the "where to place markdown" column.
Also, I cannot seem the markdown for strikethrough to work by adding --around the text. I'd appreciate any tips on new markdowns...
