"Expand all" button gone?

I stopped seeing the button today. Is it on vacation again?

No vacation planned until August for collapse button. Can you try CTRL+F5 a few times? It sounds to me like you might have some ‘old code’ cached on your system. let me know if that works. Thanks!

It’s back today! Thanks for responding.
