Hi @anilankola ,
Thank you for reaching out!
Such issues with sliders that do not load instantly are usually a side-effect of a NitroPack feature (enabled in Ludicrous mode) that delays the loading of some resources until there is a user interaction detected. This feature usually works great for sites not built to rely heavily on JavaScript.
Here are two possible solutions for the slider to load before user interaction.
1) You can switch to Strong Mode via https://nitropack.io/user/settings , however, keep in mind that this will bring down the scores.
2) If the above suggestion is not working for you, I would suggest submitting a ticket so our Technical Support team can exclude the slider from optimizations for you – https://support.nitropack.io/hc/en-us/requests/new
Keep in mind that sliders are JavaScript reliant, which means that if they show up early during page load, this will affect the scores a bit.
