Profiles need to be imported to the cloud once, not individually to every Lightroom app that uses the cloud. I don’t use Android, so I don’t know if Lightroom for Android can import profiles directly, but the standard way to do this is to install Lightroom (desktop) on your local computer. Lightroom has a menu to import presets and profiles, so import the Lightroom Classic profiles into Lightroom. They will sync to the cloud and will then be available in Lightroom Mobile too.
