Pagination next/prev Jump, not working

Question

In template file Magento_Theme/templates/html/pager.phtml the following code is never displayed:

<?php if ($block->canShowPreviousJump()): ?>
    <li class="item">
        <a class="page previous jump" title="" href="<?= $block->getPreviousJumpUrl() ?>">
            <span>...</span>
        </a>
    </li>
<?php endif;?>
<?php if ($block->canShowNextJump()): ?>
    <li class="item">
        <a class="page next jump" title="" href="<?= $block->getNextJumpUrl() ?>">
            <span>...</span>
        </a>
    </li>
<?php endif;?>

I am testing this in a category that has 35 pages of listing products. I'm browsing random pages.

I have also tried changing Pagination Frame and Pagination Frame Skip in magento configuration.

How does pagination jump work? What should I do to make it visible?

Answer 1

What version of 2.3 are you on? 2.3.3 has a bug if you're using trailing slash / instead of a .html prefix is causing queries not to run. They apparently are actively working on a solution. 2.3.2-p2 is not experiencing this. Hopefully this will be fixed in 2.3.4 if they can agree on a fix:

I didn't find any solution to this so I created a custom pager.phtml file, with the following changes:

<?php
if(isset($_GET["p"])){
    $current_page = $_GET["p"];
}else{
    $current_page = 1;
}
$last_page = $this->getLastPageNum();
$nextJumpLimit = $last_page-2;
$previousJumpLimit = 3;
$previousJump = 0;
$nextJump = 0;
if($current_page > $previousJumpLimit){
    $previousJump = 1;
}
if($current_page < $nextJumpLimit){
    $nextJump = 1;
}
?>

<?php if ($previousJump == 1): ?>
    <li class="item">
        <a class="page previous_jump" title="" href="<?php echo $block->getPageUrl($current_page-2); ?>">
            <span>...</span>
        </a>
    </li>
<?php endif; ?>

<?php if ($nextJump == 1): ?>
    <li class="item">
        <a class="page next_jump" title="" href="<?php echo $block->getPageUrl($current_page+2); ?>">
            <span>...</span>
        </a>
    </li>
<?php endif; ?>

I'm posting this here, in case it helps somebody out there.
