Why is the same ad on the device in all applications?

Question

contextual advertising

My wife has a real problem! The second month advertising city mobil in the phone, especially on YouTube!
At first it all started with YouTube, but then in VK stories, Instagram posts, mail, and even in the delivery club, they offered to exchange points for a trip in this unfortunate taxi service !!!
This is some kind of psychological attack even for me) In the settings, they made priorities in advertising and complained about advertising, anyway, it haunts everywhere from the phone! With accounts on a computer and tablet, this is not the case.
Maybe someone came across, knows how to get rid of this sect?
