Connect Shopify to Instagram + Facebook Stores

Hi there,

I have a Shopify store, and until recently, I was able to tag my brand"s products on Instagram to make my Instagram shoppable. Lately, Shopify and Facebook says there is a problem with the connection. My accounts and catalog are no longer synced. I don't know why and can't figure it out.

I need an expert to help me reconnect my Shopify products/catalog to my business Facebook and Instagram accounts. Mainly, so I can tag my products on my brand Instagram feed. Thank you
