Is the Immediate Playback of Events Changing Children’s Memories?

Memories in an active state are malleable--things that happen, emotions you experience etc. are prone to influencing the content of the memory. Eventually it gets "filed away" in a dormant state and doesn't change much unless it's reactivated, which can be triggered by vivid, related experiences. (Interestingly, there's research which shows that a reactivated memory becomes malleable again for as long as it is active, so current events can influence how you remember past ones.)

The theory in the article seems to line up with this, if you immediately view a video of something you just did, the memory is still malleable and you're more likely to remember it in a third person rather than first person context. If you view the video a few days or a week later, the memory may not be as malleable as it was at the time of creation. Curious as to why you disagree with this, do you disagree with the underlying theory?

It kind of does. Each time you recollect something you change the memory of the event (this is also mentioned in the article). Repeated recollection can have varied effects from (simplified) "I don't recall the original event, I recall the last time I thought of it" all the way up to creating false memories. I think there's been quite a bit of research on how this relates to interrogation techniques and the reliability of eyewitness testimony.

Toggling each option, it seems that third party trackers are likely what's triggering it. I still don't get a paywall but I get all sorts of other spam on the page loading - I'm assuming they give 'x' free page views per tracked ID. So perhaps search for a plugin that can achieve similar anti-tracking functionality, or use Brave. If you go that route, the options are on the lion icon - top right. They toggle per site if you want to do something like disable/enable tracking/scripts etc for a single domain.
