In case anyone else has the same problem I did...
I wanted to opt out of tumblr's new abyssmally tone-deaf and reprehensible scheme to scrape their users' content to sell to their generative AI business partners, but neither app or desktop version showed the toggle, despite updates.
For me, what finally worked was to go to tumblr.com/settings/blog/x (where x is the username of your blog) in a web browser and scroll all the way down.
There I finally found the toggle to opt out.
Please opt out, in solidarity with artists and writers and other creatives, to protect yourself - and to send the higher-up a clear message that we tumblr users aren't "content", and our posts are not for sale.
