We re-consider recent measures of $R_{ K}$ and $R_{ K^*}$, now compatible with the Standard Model expectations, as well as the results for the process $\text{ BR}(B_s \rightarrow \mu^+ \mu^-)$ alongside earlier determinations of $R_{ D^{ (\ast)}}$ and $\text{ BR}(B_c \rightarrow \tau \nu)$. We provide analytic constraints on the associated Wilson coefficients in both the $b \to s$ and the $b \to c$ sectors. These allow us to estimate the scale of potential New Physics for generic extensions of the Standard Model. We then use the results to constrain the leptoquark landscape.
