  In recent years, significant experimental indications that point towards
Lepton Flavour Universality violating effects in B-decays, involving $b \to c
\tau \nu$ and $b \to s \ell^+ \ell^-$ have been accumulated. A possible New
Physics explanation can be sought within the framework of R-parity violating
Supersymmetry, which contains the necessary ingredients to explain the
anomalies via both leptoquark, tree-level exchange and one-loop diagrams
involving purely leptonic interactions. In addition, an approximate $U(2)^2$
flavour symmetry, that respects gauge coupling unification, successfully
controls the strength of these interactions. Nevertheless strong constraints
from leptonic processes and $Z$ boson decays exclude most of the relevant
parameter space at the $2 \sigma$ level. Moreover, R-parity violation deprives
Supersymmetry of its Dark Matter candidates. Motivated by these deficiencies,
we introduce a new gauge singlet superfield, charged under the flavour symmetry
and show that its third-generation, scalar component may participate in loop
diagrams that alleviate the above-mentioned tensions, while at the same time
reproduce the observed relic abundance. We obtain a solution to both anomalies
that is also fully consistent with the rich Flavour and Dark Matter
phenomenology. Finally, we assess the prospect to probe the model at future
experiments.
