Instagram has announced that it is adding the ability for companies and creators to create
Instagram Ads without connecting to a Facebook Ad account. This feature is only available for brands and creators that have not promoted posts earlier. Companies that are promoting a post from their Instagram business account for the first time will not need to connect to a Facebook ad account or Facebook Page.

Instagram also said that that the new feature is not related to the ongoing Facebook ad boycott campaign where companies are boycotting Facebook ads over its role in the spread of posting misleading information and hate speech.
