When you optimize images, add lazy loading, or asset preloading, you might notice a drop in your speed score. This typically occurs because new images have not been cached in your store yet, and it can take up to 48 hours for those images to be cached.
If you still observe a drop in your speed score after 48 hours, it indicates that the issue lies elsewhere. Please reach out to our team to investigate the potential cause.
Additionally, please note that TinyIMG cannot decrease your store's speed; we can only improve it.
