GUYYYYYS, I FINALLY HAVE A SOLUTION. After reading all these comments and not a single solution I decided to answer you. I got THE SAME PROBLEM, I was desperate and then I finally did it. Here is how, hope u'll understand: I created my business manager account (NOT PERSONAL ONE!!!! with the name of your store), got my fb page, ig all connected to it and then in my business manager account I created an add account, put my debit card info and THEN it popped out in my shopify, it that bar Add Account, and it was all done. I wont lie to you when I say it was a nightmare setting this thing up, but this worked for me. Hope it will help you as well.
