JetPack and AMP

CLS has nothing to do with your disks; it’s a measure of how much stuff moves on the page as it’s being built. Among others, see https://web.dev/cls/

CLS is usually either a theme issue or the way you’ve built your site.

The theme I use is dynamic to the user’s screen resolution. JetPack AMP support seem to be nonexistent so maybe they should update their package literature.

I recommend asking at https://www.ads-software.com/support/plugin/jetpack/#new-post so the plugin’s developers and support community can help you with this.
