When placing code in the Miscellaneous HTML portion of the design settings, it saves successfully however the code doesn't actually end up being placed in the footer before the body closing tag.
Is there a fix for this?

Thank you @OST Agency.
I actually visited this thread (http://magento.stackexchange.com/questions/100673/miscellaneous-html-not-showing) in StackExchange and found a solution to this Magento 2 problem.
Instead of pasting the script in Stores > Configuration > General > Design > Footer > Miscellaneous HTML, I pasted in Stores > Configuration > General -> Design -> HTML Head -> Miscellaneous Scripts and it worked!
Hope this helps someone else.
