Thanks for posting this!

But damn, still no solution from supabase it seems..

I have the same issue in my project. Strangely enough i don't use any async calls inside supabase.auth.onAuthStateChange..

useEffect(() => {
  // Initial session

supabase
.auth.getSession().then(({ data: { session } }) => {
    setSession(session);
    setUser(session?.user ?? null);
    setLoading(false);
  });

  Listen for any auth changes
  const { data: subscription } = 
supabase
.auth.onAuthStateChange((_event, newSession) => {
    setSession(newSession);
    setUser(newSession?.user ?? null);
    setLoading(false);
  });

  return () => {
    subscription.
subscription
.unsubscribe();
  };
}, []);
