$\boldsymbol{b\to s\ell\ell}$ global fits after Moriond 2021 results.

We perform a model-independent global fit to $b\to s\ell^+\ell^-$ observables to confirm existing New Physics scenarios and to identify new ones emerging from the inclusion of the updated LHCb measurements of $R_K$ and $B_s\to\mu\mu$. Our analysis updates arXiv:1903.09578 and confirms this analysis: the presence of right-handed couplings encoded in the Wilson coefficients $\mathcal{C}_{9'\mu}$ and $\mathcal{C}_{10'\mu}$ remains a viable possibility and we still observe that a lepton-flavour universality violating (LFUV) left-handed lepton coupling ($\mathcal{C}_{9\mu}^{\rm V}=-\mathcal{C}_{10\mu}^{\rm V}$), often preferred from the model building point of view, accommodates the data better if lepton-flavour universal New Physics is allowed, in particular in $\mathcal{C}_{9}^{\rm U}$. The LFUV observable $Q_5$ offers a very interesting possibility to separate both types of scenarios.
