Yeah, as a cosmologist my reading of the DES results is exactly the opposite than what the article mentions - new DES results seem to show that one mystery (low values of S_8 in the low redshift measurements) was actually resolved..
The problem was that the green (CMB/Planck) and gray (weak lensing) curves in the past were not overlapping as well as they are now. To me the tension seems to mostly go away now.
See the bottom of their Fig 14 in https://www.darkenergysurvey.org/wp-content/uploads/2021/05/...
