Is there a way to create a poll on a community page? I just did a search on the forum and the results are from several years ago so I wanted to check if this has been updated since?
Basic polls are available built in to Lithium. You can surface these polls across the whole community or only selected areas. Keep in mind that you might need to add the poll widget into your page layout if you have removed it from the OOTB page layout.
The "Studio" option is only available on your community staging instance. You would need to make the changes there, verify it's working correctly and then push to your production instance. See this workflow visualized and explained in the article "The Studio Publish workflow"
