• I used youtube data api returning search result. And to get more result, I used nextPageToken as param. => when a btn i made clicked, showing next page's 5 videos.
• It actually works, but some next page results contain previous page's videos.
• I expected if 3rd page videos are a, b, c, d, e, 4th page items are f, g, h, i, j.
• but 4th page's like a, f, g, h, i or something. I'm not sure there is any rules or not.

search = async (input) => {
    const response = await fetch(
      `https://youtube.googleapis.com/youtube/v3/search?part=snippet&q=${input}&type=video&maxResults=15&key=${this.key}`,
      this.requestOptions
    );
    return await response.json();
  };

loadMore= async (searchToken, inputValue) => {
    const response = await fetch(
      `https://youtube.googleapis.com/youtube/v3/search?part=snippet&q=${inputValue}&type=video&pageToken=${searchToken}&key=${this.key}`,
      this.requestOptions
    );
    return await response.json();
  };

has anyone experienced and solved this problems?
