As quoted from the linked post.
It looks like you’re part of one of our experiments. The logged-in mobile web experience is currently unavailable for a portion of users. To access the site you can log on via desktop, the mobile apps, or wait for the experiment to conclude.
This is separate from the API issue. This will actually BLOCK you from even viewing reddit on your phone without using the official app.

as a sex worker rights supporter (plus, my best friend is a sex worker) it’s honestly kind of scary to see both Twitter and Reddit destroy themselves (at the same time). Mostly because Twitter and Reddit (especially Twitter) are the only places left on the Internet for sex workers to simply exist in the post-FOSTA world that we live in (thanks Kamala Harris!)
