An odd Siri behavior regarding Wikipedia articles

Forum
iOS & iPadOS

Hi all,
So, very recently, I noticed that when I asked Siri to search something up on Wikipedia, it would read normally, until when it asks whether I want it to continue. But then when I said yes, Siri just responded with something like 'that's what I thought', instead of continuing to read the Wikipedia article.
Visually, I also noticed that the Wikipedia article content seems to be missing in the Siri window for many of the articles I asked Siri to look up, E.G Mount Everest. But for some others like Windows 10 Siri read the article just fine and the article is visible visually.
I wonder, what has gone wrong with Siri very recently? I never experience this at all in the past, up until very recently.
