My description of the lesson’s error
I receive multiple errors saying “Non-optional” widget binding “Host” (or) “Join” not found.
I’d say these errors are due to the UButtons *pointers not actually being bound to the corresponding widgets yet.
edit: It seems that I was semi-right, after looking at the documentation I was right about the pointers not being bound.
However I did not know yet why this was the case.

In this lesson your buttons definition is in a private section…only work in a public section
class PUZZLEPLATFORM_API UMyUserWidget : public UUserWidget
{
GENERATED_BODY()
public:
UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
class UButton* Host;
UPROPERTY(BlueprintReadWrite, meta = (BindWidget))
class UButton* Join;
};Ah, yes, theses should be at least protected I think.
