The following questions were put and comments made:
Emmanuel Saridakis: Can the same G_eff behavior solve simultaneously sigma_8 and H_0 tension?
Houri Ziaeepour: Comment: Planck data has internal inconsistency. Therefore it is too soon to search for new physics to solve it.
Houri Ziaeepour: Probably the problem comes from modelling of lensing of the LSS.
Houri Ziaeepour: For instance interaction in the dark sector may explain some of inconsistency.
