The rate of semitauonic $B$ decays has been consistently above theory expectations since these decays were first measured. Recently significant differences between the forward-backward asymmetry in $B\rightarrow D^∗e\nu$ and $B\rightarrow D^∗\mu\nu$ were also reported. Belle II data is well suited to probe such anomalies. The low-background collision environment along with the possibility of partially or fully reconstructing one of the two B mesons in the event offer high precision measurements of semileptonic $B$ decays. This talk presents recent Belle II results on lepton flavor universality tests based on inclusive decays.
