Message notifications are indeed a difficult problem, especially when users have many relays available.
Discussion
Based on our experience, push notifications are quite stable when you use Keychat’s default relays, although a very small number of missed alerts is still unavoidable.
I never touched the settings. Are they ok or should i remove one?
It’s okay. I just sent you some ecash sats via Nostr DM; you can receive them on the Keychat wallet page. After that, send a few ecash sats to your chat partner as well. Once you have an ecash sat balance, every message you send automatically carries an ecash sat stamp, and the Keychat relay will forward it. Because the Keychat relay is our own relay, messages sent through it let your chat partner receive notifications more reliably. Please don’t think we’re forcing anyone to use the Keychat relay—we’re still looking for ways to make message notifications even more stable.
Additionally, our current notification system relies on certain Google services, which GrapheneOS may disable. We’re still working on a solution.
