What should I do if I want inject one store and use it by context?

Is there anyone can help me? That will be appreciated.

Forgive me, I'm a bit rusty on this. The issue is fixed if you remove <Observer>. I'm not sure if this because of a problem with Observer, the way you're using it or a Preact 10 compatibility issue.

You can do this as an alternative:

const App = observer(() => {
  const store = useStore();
  return (
      <div>{store.a}</div>
  );
});

Thanks! Can useMemo and useCallback work when component is be wrapped ?
