  We update the standard model (SM) predictions of $R(D^*)$ using the latest
results on the decay distributions in $B \to D^* \ell \nu_{\ell}$ ($\ell = \mu,
e$) by Belle collaboration, while extracting $|V_{cb}|$ at the same time.
Depending on the inputs used in the analysis, we define various fit scenarios.
Although the central values of the predicted $R(D^*)$ in all the scenarios have
reduced from its earlier predictions in 2017, the results are consistent with
each other within the uncertainties. In this analysis, our prediction of
$R(D^*)$ is consistent with the respective world average at $\sim 3\sigma$. We
have also predicted several angular observables associated with $B \to D^* \tau
\nu_{\tau}$ decays. We note that the predicted $F_L(D^*)$ is consistent with
the corresponding measurement at 2$\sigma$. Utilizing these new results, we fit
the Wilson coefficients appearing beyond the standard model of particle physics
(BSM). To see the trend of SM predictions, we have utilized the recently
published preliminary results on the form-factors at non-zero recoil by the
lattice groups like Fermilab-MILC and JLQCD and predicted the observables in $B
\to D^* \ell \nu_{\ell}$, and $B \to D^* \tau \nu_{\tau}$ decays.
