Welcome to the Q&A Forum

I haven't had any trouble using JSON-LD for organizations and people. I have only used in-line product schema so far for products. You could try adding the in-line markup if you haven't already, and leaving the JSON-LD script up.

Still having some issues with this. Would anyone be able to help?

Hi Justin, Some of our team picked up on this question and asked me to send you a quick response. In Schema.org markup, you only should declare one product per page, and you have two. Although the Rich Snippets testing tool will say the markup is “All good”, Rich Snippets will not show in the SERP. Then, it looks like your individual reviews aren’t nested correctly inside of the schema.org/Product tag – that could be causing an issue as well. We’ll follow up with you through our Support team! Definitely want to get this working with you.
