Flow doesn't match my tastes anymore

Hi everyone,
I already contacted the support, but I got no useful answers.
Since a few weeks, I’m receiving bad recomandations in my flow.
Today it was HORRIBLE!!!
My music is mainly on 70s, 80s and Pipe Organ music.
Now I’m receiving a lot of contemporary “music” suggestions that are just garbage for my tastes!
They said that I have used a “pirated app” in May 2023, which is not true. Never installed any app in my Android devices outside of Google Playstore.
Maybe they are referring to my Linux player which is unofficial since Linux is not supported by Deezer (That’s a shame!). But of course how an unofficial software should affect my favorites that are the basis for the My Flow content?
I’m more convinced that they changed something on their algorithm that is messing up all the recomendations.
Does anyone experienced in the last period any intrusion from unwanted music that is totally unrelated with your favorite music?
