Hello @PedroChagasGuerra

Thank you for your report

We have rechecked the reported issue on the latest 2.4-develop.
We have created two Categories and added two products to each

The GraphQL query

query {
  products(filter: { category_id: { in: ["3", "4"] } }) {
    total_count
    items {
      sku
      name
    }
  }
}

returned all 4 products

{
  "data": {
    "products": {
      "total_count": 4,
      "items": [
        {
          "sku": "Product 2 from Category 2",
          "name": "Product 2 from Category 2"
        },
        {
          "sku": "Product 1 from Category 2",
          "name": "Product 1 from Category 2"
        },
        {
          "sku": "Product 2 from Category 1",
          "name": "Product 2 from Category 1"
        },
        {
