This guide helps when Instagram setup does not finish. The most common fixes are switching the account to a professional profile, approving the permission window, and checking whether your Facebook Page link is set up the way your team expects.
Instagram must be a professional account before it can be connected here. Most failures happen because the account is still personal, the permission window was cancelled, or the team expected a Facebook Page link that is not set up yet.
A personal profile can sign in to Instagram, but it cannot be connected here until it is switched to a professional account.
If the permission window is closed or denied, Instagram sends you back without finishing the connection.
This can happen right after switching account type, or when the team expects Facebook-linked tools that have not been connected yet.
If you retry from an old popup or stale callback page, the connection can fail again right away. Start a completely new attempt.
