We have been able to decrease the Cumulative Layout Shift (CLS) score by 95% on average. This is a significant improvement from before and may provide a boost in SEO as search engines such as google factor in CLS as one of the performance metrics for page speed ranking. This improvement will also provide a better user experience for your customers while the app is loading.
