Abstract This presentation reviews the first measurement of R(X) at the Y(4S), the first measurement of R(D*) at Belle II, the tests of light-lepton universality in angular asymmetries of B -> D*lnu, and the test of light-lepton universality in inclusive semileptonic B meson decays. All results are based on 189/fb of Belle II data.
