Since I use/e/OS and activated trackers filtering, I felt like every advertisement screen is blocked. But since about 2 months, Radio France app manages to display an advertisement on its startup. It adverts for unrelated products like any sold in a supermarket.
This app is evaluated 4/5 stars, and 0/10 for privacy.
Advanced Privacy looks like not logging this ad display as an allowed tracker, nor as a blocked one. I wonder if there is a tracker or not, and how a new tracker could be detected, then reported.
It might be that AP Tracker Blocker does not have the source of this advertisement on its list.
(You could try a curated VPN service or an app like personalDNSfilter that utilizes the VPN-interface of the device to see if that can block the ad…)
It might as well be that the app delivers this ad via other means, so it can not be blocked by AP per design.
An ad is annoying but is not necessarily a tracker (in my understanding).
Thank you for the instructive link. So, Adaway or Exodus filters do not block these ads; maybe because of the app hidding them with DoH or DoT request. Meanwhile, others reasons are possible.
For adaway it might depend on the filterlist … Or the ad might just be “hardcoded” or be delivered from radio france adresses … There are certainly ways to bypass DNS filtering…
