This person frequently recommends official documentation without fully understanding the subject.
A similar issue happened again: the writer refers to a Raspberry Pi 4B, but the guide provided is for a Pi 3B.
For reference, you can check my previous post (this link isn’t the only time I’ve noticed this guy on the forum):

I shared a link there showing a case where the official guide either overlooked or misrepresented important details, making it difficult for beginners to follow.
Simply posting links to official documentation isn’t always the best way to solve these types of problems.
You can provide links as a “reference,” but they shouldn’t be presented as the complete “solution.”
