Comic shear is a powerful probe of growth and geometry in the Universe, yet its analysis is challenging and requires compelling robustness tests in light of cosmological tensions. In this talk I will first present a work in preparation of the DES Y3 cosmic shear analysis in harmonic space to evaluate its (in)consistency with real space analysis (arXiv:2011.06469). I will then present internal consistency tests of the DES Y1/Y3 multiprobe analysis combining shear and clustering (arXiv:2011.03410). Finally, I will briefly present some predictions for the upcoming analysis of DES Y3 with CMB lensing (SPT+Planck) for LCDM and non-parametric growth studies.
