We tested several phenomenological extensions of the ΛCDM with the newest datasets from the chain CMB+BAO+SNIa, to see whether they are able to alleviate the aforementioned tensions. We find that when the updated version of the Planck CMB likelihood (PR4 LoLLiPoP and HiLLiPoP), with respect to the more used likelihoods (PR4 CamSpec and PR3), is considered, the lensing anomaly is reduced, and the preference for AL > 1 and Ωk < 0 is less significant. From the CMB+BAO+SNIa dataset, in the context of the parameterization w0waCDM, we find a preference for a time-evoling dark energy over the rigid cosmological constant which is consistent with the most recent results from DESI collaboration.
