             abstract = "We investigate a well known scenario of interaction in the dark 
                         sector where the vacuum energy is interacting with cold dark 
                         matter throughout the cosmic evolution in light of the cosmic 
                         microwave background (CMB) data from final Planck 2018 release. In 
                         addition to this minimal scenario, we generalize the model 
                         baseline by including the properties of neutrinos, such as the 
                         neutrino mass scale (M\ν) and the effective number of 
                         neutrino species (Neff) as free parameters, in order to verify the 
                         possible effects that such parameters might generate on the 
                         coupling parameter, and vice versa. As already known, we again 
                         confirm that in light of the Planck 2018 data, such dark coupling 
                         can successfully solve the H0 tension (with and without the 
                         presence of neutrinos). Concerning the properties of neutrinos, we 
                         find that M\ν may be wider than expected within the 
                         \ΛCDM model and Neff is fully compatible with three neutrino 
                         species (similar to \ΛCDM prevision). The parameters 
                         characterizing the properties of neutrinos do not correlate with 
                         the coupling parameter of the interaction model. When considering 
                         the joint analysis of CMB from Planck 2018 and an estimate of H0 
                         from Hubble Space Telescope 2019 data, we find an evidence for a 
                         non-null value of the coupling parameter at more than 3\σ 
                         confidence-level. We also discuss the possible effects on the 
                         interacting scenario due to the inclusion of baryon acoustic 
                         oscillations data with Planck 2018. Our main results updating the 
                         dark sectors' interaction and neutrino properties in the model 
                         baseline, represent a new perspective in this direction. Clearly, 
                         a possible new physics in light of some dark interaction between 
                         dark energy and dark matter can serve as an alternative to 
                         \ΛCDM scenario to explain the observable Universe, mainly in 
                         light of the current tension on H0.",
