> Four values are particularly problematic: the speed of the expansion of the Universe today, the magnitude of matter density variations within the Universe, and the temperature variations and trajectory of the primordial light of the Universe.

Problematical? No.

> The first inconsistency concerns the speed of the expansion of the Universe. We can measure this speed either through supernovae or through the light of the cosmic microwave background (CMB). But these two measurements give a result that differs by more than 10% which cannot be explained by observational errors.

Again, No. Let me check.

The discrepancy is 3%, which is well within the limits of observational errors.

My guess is that the new paper has overestimated the intrinsic observational accuracy of the supernova results.
