Ask HN: YouTube keeps switching watch history back on

I have had my watch history off for months, and one day recently it was automatically turned on again.

Then I went into "YouTube History" and changed the control again, about 2 weeks ago. For about two weeks it was set to off, but then yesterday evening I noticed that history was switched on again.

Has anyone else noticed this? I do not think it's done by accident from my side, as the history control is not possible to do via apps, etc. One has to go into a separate Google webpage in order to explicitly turn history off.
