CSS not loading on generated PDF

Hello,

There's some issue ocurring when snappy creates the PDF, and the CSS supose to load on the view is not working.

This is the view with the correct CSS:

And this is the generated PDF:

The snappy code is configured this way:

public function createWithMultipleKits(Collection $kits, $disk = "local")
{
    $base_path = self::BASE_PATH . "/many";
    $size = ['100mm', '80mm'];
    $snappy = $this->configHtmlToPdf($size);
    $filename = 'etiquetas_internas_' . Str::random('6');
    $fileFullLocation = $base_path . "/{$filename}.pdf";
    $renderTicketHtml = view("pdfs.kit.ticket.index", ["kits" => $kits->map(function ($kit) {
        return [
            "id" => $kit->id,
            "number" => $kit->number,
            "type" => $kit->kit_type->name,
            "batch" => $kit->batch,
            "qrcode" => QrCode::generate(env("APP_FRONTEND_URL") . "/cadastrar-kit?kit_number=" . $kit->number)
        ];
    })->toArray()]);
    if (Storage::disk('local')->exists($fileFullLocation)) {
        Storage::disk('local')->delete($fileFullLocation);
    }
    $snappy->generateFromHtml($renderTicketHtml, storage_path("app") . "/" . $fileFullLocation, ['encoding' => 'UTF8']);
    return [$fileFullLocation, "$filename.pdf"];
}

private function configHtmlToPdf($size = ['100mm', '100mm'])
{
    list ($heigth, $width) = $size;

    $snappy = new Pdf('wkhtmltopdf');
    $snappy->setOption('header-spacing', '0');
    $snappy->setOption('enable-local-file-access', true);
    $snappy->setOption('margin-top', '0mm');
    $snappy->setOption('margin-bottom', '0mm');
    $snappy->setOption('margin-left', '0cm');
    $snappy->setOption('margin-right', '0cm');
    $snappy->setOption('header-font-size', '3');
    $snappy->setOption('footer-spacing', '5');
    $snappy->setOption('footer-line', true);
    $snappy->setOption('footer-font-size', '3');
    $snappy->setOption('page-height', $heigth);
    $snappy->setOption('page-width', $width);

    return $snappy;
}

The CSS is coded directly on the view file (inside the head tag).

Could it be because wkhtml2pdf has some issues with flexbox.
If so check here for more info https://stackoverflow.com/questions/57020675/using-flex-css-with-wkhtmltopdf
