The new one is so watery 
and using less water or refrigerating doesn’t seem to help. Batch on my new bags is “1L: 95860”.
Found it - the Huel “outlet” let’s you buy the old versions. I’ve cancelled my subscription and I’ll get it from here as long as I can.
I’m getting some old Huel Vanilla from the Outlet. Whenever they run out of it then I’m not buying anymore.
