    • Magento 2.4.x affects all themes, not just Luma or Blank. Custom, premium, and bundled-theme extensions can break because of updated layouts, JS libraries, and PHP changes.
    • Most issues come from outdated overrides, including old XML layouts, deprecated JavaScript, and outdated CSS assets that no longer match Magento 2.4.x’s front-end structure.
    • Search, product pages, and category pages are the most affected areas, especially when themes use custom swatches, galleries, filters, or AJAX features.
    • Keeping your theme and Magento 2 extensions updated and testing upgrades in staging environments is the best way to avoid theme breakage after updating to Magento 2.4.x.
