Common pitfalls

1. Not using a backplane for multiple server instances - Messages only reach clients connected to the same server

1. Forgetting token refresh handling - WebSocket connections don't automatically refresh tokens

1. Blocking Hub methods - Use async/await, don't block the Hub thread

1. Not handling reconnection state - UI should indicate connection status

1. Sending too much data - Use streaming for large payloads, batch small updates

1. Not grouping by tenant in multi-tenant apps - Security risk of cross-tenant notifications

1. Missing Service Worker for offline/background - Users miss notifications when app isn't focused
