Ya, you have to enable notifications because that's how they run in background. It's a little slower than some other NWC solutions, but it's a reliable mechanism that doesn't require any user interaction. And that's what's important in an NWC wallet.

Everyone I know running GrapheneOS is constantly complaining about shit regular android users can do, but which doesn't work on Graphene. Someone was telling me just yesterday that they couldn't lock their phone. Apparently, that function just doesn't exist in Graphene. I get the privacy and open source thing, but at some point you have to prioritize usability. Otherwise, why even bother?
