Why Do Perplexity’s Sources Sometimes Seem Unrelated to Its Answer?

I’ve noticed that a Perplexity answer can include a source that looks relevant at first, but the cited page doesn’t clearly support the specific claim beside it. Is this usually a problem with how the answer is summarized, with the page itself, or with how citations are matched to individual statements?

I’m curious whether others have found a reliable way to check Perplexity citations without having to reread every result from scratch.
