Recently, I was working for a client that was using Magento 2.4.5-P2 with Codazone theme. The problem was on the category pages. Pagination was missing. I found an issue that they were overriding the list.phtml file.
To fix this simply open your theme’s list.phtml file and find the code
<?= $block->getToolbarHtml() ?>
Replace this with the code below:
<?= $block->getChildBlock('toolbar')->setIsBottom(true)->toHtml() ?>
That fixed our problem.
