Why can't I try the sample code of HTML?

Question

I'm learning HTML. But I have a problem.
On lesson 2.1, when I tap sample codes to try them, the advertisement of Sololearn Pro appears and prevents me from trying (I have a free account). However, I can try sample codes on lesson 1.1 without the advertisement. Could anyone tell me the reason?

However, if I tap "Tap to try", the advertisement with "Invest in your learning with pro" appears. I cannot understand why because I could try sample code on HTML lesson 1.1 and Python lessons.

Answer 7

I tried again, only to fail…
…Maybe I must get pro account?
