Oh yes, I remember. Suddenly moving all the parts of my body independently of each other was very difficult for me. And I also had to pay attention to the styling of my hands and feet at the same time, and, above all, smile while doing all of it.

All that was very difficult for me.
The only difference is that I was talking about myself and my problems. In your posts, however, you generally describe certain tango moves as difficult, even though they are beginner stuff. You don't say whether they are difficult for you personally, or for someone else. In such a case, we could find advice here.
