Next.js Image Component Not Preloading WebP Images Correctly on Mobile Devices

nextjs image webp performance javascript

I'm having a hard time understanding I'm trying to configure After trying multiple solutions online, I still can't figure this out..... I'm sure I'm missing something obvious here, but I'm working with a strange scenario where the Next.js Image component does not seem to preload WebP images correctly when viewed on mobile devices. I'm using Next.js version 12.0.7 and have configured my images for optimal performance by specifying the `priority` attribute. However, when I inspect the network activity on mobile, the WebP images are either not being fetched at all or taking significantly longer to load compared to JPEG images. Here's a simplified version of my code: ```jsx import Image from 'next/image'; const MyComponent = () => { return ( <div> <Image src="/images/example.webp" alt="Example Image" width={600} height={400} priority /> </div> ); }; export default MyComponent; ``` I've tried adding the `loading="eager"` attribute, but that didn’t change anything. I've also checked the `<link rel="preload">` tags in the `<head>` of my document and confirmed that the WebP images are listed there. Interestingly, when I test the same implementation on desktop, the images load almost instantly. I’ve also ensured that the images are properly optimized and the server supports the WebP format. I've logged the network requests in Chrome DevTools and it's showing a status of 200 for the WebP images, but they still take longer to display compared to other formats. I’m not seeing any console errors or warnings that could provide insight into this scenario. Is there a known limitation with the Next.js Image component related to mobile devices and WebP image preloading, or is there another configuration I might be missing? Any suggestions would be greatly appreciated! My development environment is Windows. What am I doing wrong? Is there a better approach? My team is using Javascript for this application. What am I doing wrong? I'm coming from a different tech stack and learning Javascript. Has anyone else encountered this?
