Note about Squarespace Embed:
As of July 2019, your Squarespace account requires a Premium subscription to be able to use the "Code Block" feature on pages and "Code Injection" access in the site settings to install the Squarespace Ajax code in your site's footer. The Premium plan is $6 more a month, but it may be possible to upgrade the plan, make the changes outlined here, then downgrade. You will lose access to edit those features but what you changed will remain on your site.

Be sure to paste this code into the Footer and not the Header. Here is the difference:
