Bluntedobjects review for Instafeed ‑ Instagram Feed

I was glad to see that Instfeed integrated with Shopify, as it was pretty confusing for me (someone who doesn't know coding). But the customizations are so limited, I find myself googling how to modify the code to get it to display the way I want. Especially for the mobile version, it's showing up as one photo per row and huge, so unattractive! Please help fix this.
