I also noticed this on 2 accounts - did not take as careful notes as you did unfortunately. But I'm fairly confident - both of these are accounts where I care about the interactions not being used for training.

What's kind of still an open question for me is if the toggle automatically also applies to my Codex CLI use on the same account, or if that data is still silently being used in some way.

After this happened, I deleted all my ChatGPT history (even though I'm not sure how much it helps at this point), but for Codex I still haven't really found any way to do the same, I can still load my past sessions even after archiving them.
