Harmless but disturbing strange behavior: my notebooks started showing cell numbers that increment by 2… The first cell executed is [2], then [4], etc. Anyone seen this before? Can I fix it?

Ooh I found a [duplicate entry of this issue](https://discourse.jupyter.org/t/cell-numbering-broken-on-new-jupyter-lab-notebook/26585/5), and it seems the Anaconda assistant extension is the culprit?

Solved. Disabling the `@anaconda/assistant` did it. Sorry for the noise, everybody!
