I noticed you updated the community forum over the weekend. While the majority of the site still seems the same for the most part - at least on mobile, I’m now unsure how to wrap code snippets in the code tag with the new formatting options toolbar.
It appears that the wrapping code feature has disappeared from the editor top bar on mobile. You can still create inline code by wrapping a line in backquotes (`), or write a code snippet by placing triple backquotes (```) on separate lines before and after the code block.
