While most of these discrepancies can be removed with the addition of new physics (NP) in $b \\to s \\mu^+ \\mu^-$, a difference of $>\\sim 1.7 \\sigma$ still remains in the measurement of $R_{K^*}$ at small values of $q^2$, the dilepton invariant mass-squared. In the context of a global fit, this is not a problem.
