Hi @Krishna12
This is PageFly - Landing Page Builder. I would love to provide my recommendations for your store based on 7 years of providing solutions for about 150,000 active Shopify merchants.
The speed score on Shopify is calculated by Google Lighthouse, so I think you might need to re-index your pages to ensure Google crawls your page and recognizes the changes you’ve made.
You can go to Google search console to reindex your pages https://search.google.com/search-console/about
I can see the main issue lies on the image size as well. You can consider reduce the size of the images a bit, especial the images on the slideshow. Or run through an image optimizer tool like https://tinypng.com/ (if you haven’t done it yet)
We have a detailed guide about page speed optimization here https://pagefly.link/xQKRAfpQ , hope it also helps.
I hope the suggestions will help you solve the problem. If you think they do help, please let me know by giving it a Like. Thank you and wish you the best of luck
