Facebook & Instagram

At first glance it's good, it promises to make it work.
But it really underdelivers. You still have to do many things in the meta account, which is terrible, I mean astoundingly terrible.
I am new to this but I'm a developer and I still don't understand anything on it. Not shopify's fault, but I really thought the facebook and instagram app would handle all of this nonsense for me. It doesn't.
Now I have a semi-connection and I don't know what to do to make it work, neither what it is supposed to do if it can't do that, great.
