We present an up-to-date complete model-independent global fit to observables that confirms patterns of New Physics able to explain the data. We include the recent LHCb measurements of
,
,
,
and
in our analysis, which now includes 254 observables. This updates our previous analyses and strengthens their two main outcomes. First, the presence of right-handed couplings encoded in the Wilson coefficients
and
remains a viable possibility. Second, a lepton flavour universality violating (LFUV) left-handed lepton coupling (
), often preferred from the model building point of view, accommodates the data better if lepton-flavour universal New Physics is allowed, in particular in
. We observe that the LFUV observable
offers a very interesting possibility to separate both types of scenarios.
