Recently, in ref. \cite{A4Datta} Datta et al. [arXiv:2106.06773] proposed an$A_4$ flavor symmetric model supplemented by $Z_2\times Z_3$ symmetry which canaccommodate the appropriate lepton mixing and neutrino masses via Type-I seesawmechanism. They have constructed a minimal model with only one $SU(2)_L$doublet scalar and six flavons that generate a specific flavor structure,favors the normal hierarchy of light neutrinos and narrows down the range ofDirac CP violating phase. Taking into account the contribution of all invariantterms, under all symmetries, is very important in the model building process,however, in ref. \cite{A4Datta} the authors miss a Majorana mass term whichcontributes to and changes the structure of the Majorana mass matrix of theright handed neutrinos. In this comment paper, we point out the above issue andprovide a solution to fill in the missing term in ref. \cite{A4Datta}.
