that Instagram will now allow advertisers for users in the US and Turkey to create Instagram ads without linking a Facebook Page.
According to Instagram:
"You can now create Instagram ads without having a presence on Facebook. If you are promoting a post from your Instagram business account for the first time, you won't have to connect to a Facebook ad account or Facebook Page."
Key emphasis here is first time users who likely didn't have their Facebook pages connected to their Instagram account just yet. However, existing businesses can't disconnect linked Facebook and Instagram accounts.
