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.

  • The API issue was a huge nail into the coffin of the user experience at reddit. For sure, mobile site will disappear and then old.reddit.

    Everything about this is utterly tone deaf, you can see it in u/spez answer in his AMA about how the company will continue to be profit driven until it’s profitable. Bro, this is not how you talk to your user base. Your actions, policies, and strategic outlook should be toward driving the user experience and your service so that it is profitable. Not degrading all things for grinding down every extra cent at the expense of your entire companies differentiators.

    Fuck spez, fuck reddit.
