@YouTube I have switched off personalised ads, but that appears to mean I am not able to report offensive pre-roll ads. There are at least two I'm seeing regularly at the moment that are just downright sexist/misogynist but I can't flag them for review!
Thanks, I haven't tried reporting there. Next time I see one of them I shall. Everything I found on line suggested I should have been able to report via "why this ad?" within the app but because I have personalised ads turned off the direct "report" option didn't appear. Thx.
