  In light of new data we present an updated phenomenological analysis of the
simplified $U_1$-leptoquark model addressing charged-current $B$-meson
anomalies. The analysis shows a good compatibility of low-energy data
(dominated by the lepton flavor universality ratios $R_D$ and $R_{D^*}$) with
the high-energy constraints posed by $pp\to \tau\bar\tau$ Drell-Yan data. We
also show that present data are well compatible with a framework where the
leptoquark couples with similar strength to both left- and right-handed
third-generation fermions, a scenario that is well-motivated from a model
building perspective. We find that the high-energy implications of this setup
will be probed at the 95% confidence level in the high-luminosity phase of the
LHC.
