                         within the \Λ cold dark matter cosmology. In particular, we 
                         analyze the MTMG model, for the first time, with the Planck-cosmic 
                         microwave background (CMB) data, and how these precise 
                         measurements affect the free parameters of the theory. The MTMG 
                         model can affect the CMB power spectrum at large angular scales 
                         and cause a suppression on the amplitude of the matter power 
                         spectrum. We find that on adding Planck-CMB data, the graviton has 
                         a small, positive, but nonzero mass at 68% confidence level, and 
                         from this perspective, we show that the tension between redshift 
                         space distortions measurements and Planck-CMB data in the 
                         parametric space S8-\ωm can be resolved within the MTMG 
                         scenario. Through a robust and accurate analysis, we find that the 
                         H0 tension between the CMB and the local distance ladder 
                         measurements still remains but can be reduced to 
                         \∼3.5\σ within the MTMG theory. The MTMG is very well 
                         consistent with the CMB observations, and undoubtedly, it can 
                         serve as a viable candidate among other modified gravity 
                         theories.",
