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.

Tbf, there are a ton of comments that I think are genuine, not projection, about the API changes and blackouts, along the lines of “who cares” and “neckbeards!”. And those are the people who haven’t moderated a subreddit, weren’t there when old. was the default, and that I’m fine with leaving behind- the commenters who might as well be spambots.
