Thanks! it depends on which browser you're using, Keychat is more restrictive for the added nostr and privacy features, I'm still not able to detect why it won't refresh and couldn't debug my client on their desktop version. couldn't play with screen off too. will try to make it work better on Keychat but it may be a trade-off for their added features so it may never work. but if you can test on other browsers it should work fine with screen off or even in background while using another app, I'm assuming you mean android.
