I tried that, and couldn’t get it working. There must be some other package I’m missing. I tried some stuff like carrier services, but no luck. Or maybe it’s the sandboxed nature of gsp, but I think there’s something else missing. There’s a dialog that launches in Lineage without gapps and Lineage with MicroG, but fails to register the feature still. But in Graphene and Calyx, that dialog never launches.
