Displaying Collection metafield definitions

[SH231]

Hi there! I have set up my Collection Metafield Definitions to display 'Additional Info' and I can see it inside the collection in Shopify however when I type my text it is not showing on my website. When I've tried to add a block or a section in the theme editor there is no option to add this data. Essentially I am trying to add below the fold content and Q&A's to each of my collection pages. Have I missed a step or is my theme not supporting the new feature? I am on Shopify 2.0. Many thanks in advance!

It should work if you put it inside a Custom Liquid block (editor) or render directly in the theme code like {{ collection.metafields.custom.yourdefinition }}
