Need help w/ FB / IG in review or does not comply

Been getting this error with my store:

This Facebook Page or Instagram account can’t be selected because it’s linked to a shop that’s still in review or doesn’t comply with our seller policies. You can try again after you review and resolve Business Support Home issues

This would be the first time this shopify store has connected with the business profile. the business profiles are 3+ years old, the shopify store about 6 months old. I have disconnected the account linked to it for the time being. Is there an easy fix here?

Thank you in advance for any of your help!

thank you both for this, @Mesh_Code and @olivia114 .

i had created a pixel before this attempt which enabled ads but not the shop. Would this be the culprit? How would I go about fixing this?
