Zustand State Not Updating in Components

1. Selector returns new object on every call (loses reference equality)
2. Not using selector hook, reading store directly
3. Store not properly exported or imported
4. Selector comparing wrong state property
5. Async state updates not properly awaited

Use Zustand selectors correctly:

import create from 'zustand';

const useStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 }))
}));

// In component
const count = useStore((state) => state.count);
const increment = useStore((state) => state.increment);

// Avoid - creates new object
const { count, increment } = useStore();
