Hello,
those pages are skipped because canonical meta tag defined in html source points to a different URL. For ex on /posts/disney-dreamlight-valley-toy-story-content-update-trailer-d23-expo-2022/amp it points to /posts/disney-dreamlight-valley-toy-story-content-update-trailer-d23-expo-2022 (without /amp)
