Just like Qualifio, Facebook is making their platform change every day. At the date of writing, one of their upcoming changes is the page, evolving towards a "New pages experience".
This new version of the pages will no longer support the custom tabs which were required to publish a Qualifio campaign on your Facebook page. We are therefore also removing the feature from our back office.
As of February 22, 2022, it will no longer be possible to publish a campaign on a Facebook tab. All campaigns previously published on a Facebook Tab will be available on a minisite via the same smart URL.
Of course, advertising of the Qualifio campaigns through Facebook Ads remains fully possible.
NB: All Facebook Tabs had been previously removed from the Pages in December 2021 by Facebook themselves.
