Am not if you are trolling on being serious. Sasuke has been absent so how do you expect her to learn it? He had fugaku around all the time so he could teach him, its not the case with sarada so its no fault of hers. You would have had a point if mayb she was taught but still cant perform it. One training session with her dad and the girl would perform it no problem. In fact the onl thing required from her is to know the handseals for it
And she isn't even out of the academy student , Sakura is strengthening Sarada mind . Remember Sakura intellect was very useful in the chin in exams, she noted Sarada has her chakra control, so ninjutsu isn't really a problem for her to learn ,
