Can you explain how you did that? I am having all the same troubles and facebook customer support isn't helping. I injected the meta pixel into my squarespace, and everything is linked on my events manager, but when I try to add the catalog using the metapixel its saying the microdata is incorrectly formatted. Then I read that squarespace doesnt need microtags? So my head hurts...if this fixed your pixel, please share a step by step 🙂
