Hi @SRVAssociations. Not having the same email address for your Constant Contact account and your Instagram account shouldn't matter. Thank you for taking the time to reconnect your account. Instagram uses the Facebook API so we will want to try some troubleshooting at the Facebook end.
We'll want to confirm the Facebook account you are logged in with is an admin, editor, or moderator for the Facebook page. You can find this on Facebook by going to the Page > Page Settings > Page Roles.
