The latest cope is “hypersonic weapons aren’t what they’re hyped up to be”.
It seems that a year ago they managed to shoot down one kinzhal missile. From my understanding, they shot it down in its “final approach”/maneuver to target stage, which happens at subsonic speed.

The actual hypersonic missiles can maneuver at hypersonic speeds, and Russia hasn’t used those in Ukraine yet.
They never shot down a Kinzhal, those sources you linked are basically Ukro propaganda cope. Russia has and continues to use hypersonics in Ukraine which neither Ukraine’s remaining legacy Soviet S300 nor their Western provided Patriot systems (multiple of which have already been taken out by these missiles) can shoot down.
It’s good to be skeptical of any claims that are extreme, and “Kinzhals have never been shot down” seems like a strong claim, like you would expect by simple random chance that one might eventually get shot down. However, I distinctly remember the ‘Kinzhal shootdown’ story, so I present you these images.
This is what a Kinzhal looks like strapped to a Russian plane
This is the 'shot down Kinzhal' presented to the media by a high ranking Ukrainian official (I forget his name)
Bonus: Another 'Kinzhal' Ukraine claimed to have shot down two months later
(It’s the same one)
