Missing option to change core count on analysis board

In the past I have seen the option to change the number of cores used in the WASM based stockfish analysis board. Lately on chrome at least this appears to be missing, bringing my NPS from 5-6 million to 1 million.



Any reason why this would be? Something on my end I need to change?

Indeed. Saw the same thing here. Delete lichess cookies, refresh and login. Should work then.
