fix(mobile): preserve channel list across background/resume reconnection#588
Merged
Conversation
When the app was backgrounded for 30s+ and reopened, the channel list disappeared behind a "Connecting…" spinner for up to 30s. Three compounding issues: 1. The background grace timer was 30s — the socket disconnected right when the user returned. Reduced to 5s. 2. onAppResumed() only reconnected when status was `disconnected`. If the session was in `reconnecting` with a long backoff timer, it just waited. Now force-reconnects immediately in any non-connected state. 3. The appLifecycleProvider listener fired refresh() on resume, which called fetchHistory() over an unauthenticated socket. The REQ either timed out (returning empty []) or was cancelled on disconnect, replacing cached channels with nothing. refresh() now bails when the session isn't connected, and build() preserves cached channels during reconnection instead of re-entering a loading state.
