How can I connect my Instagram Business account to Shopify?

[badfashion1]

Hi everyone, I have a problem to connect my Instagram Business account with shopify. It always says:

Connect the account you want to tag products with. You will see only accounts that are owned by the connected business manager.

However, the problem when I go to my Facebook account is that it says my Facebook account is already connected to my Business Manager.

Does anyone know what I can do about this?
