Get All Campaigns API doesn't get ALL campaigns


After I retrieve all the campaigns from Get All Campaigns ( by iterating until hasMore = false, I am not seeing many of the email campaigns that are available through the web interface. I am not sure how these missing campaigns differ from the ones that I do receive, they seem to all be more recent ones, as in, I see the campaigns for January and February of 2017 and the ones from 2016, but not the ones from March or April of 2017. Thoughts? Do I need to call the Get Recent Campaigns ( in addition to Get All?
