The video did not settle on the jamming of von der Leyen plane on approach to Plovdiv, but AFAIR it was a (likely unintentional) lie.
Never acknowledged by von der Leyen nor by her press secretary because it exposed the lack of basic world knowledge around von der Leyen and her office.
Why downvotes?
Here's the press conference where it was announced: https://audiovisual.ec.europa.eu/en/media/video/I-276341
FlightRadar24 disproved the story shortly after: https://twitter.com/flightradar24/status/1962565122326700178
TLDR: Neither von den Leyen nor her office knew about ADB-S nor about the multiple services that collect ADB-S broadcasts and republish, and there was none around who could stop them from announcing an embarrassing lie.
