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 main reason is that although the concessions we make may seem ever so insignificant, they pile up and dettach you from what you were looking for in the first place. You barely see your acquaintances posts on instagram or facebook anymore. Twitter is on it’s way to become a cesspool. Every new Reddit “feature” just makes the experience worse. It won’t be long for those platforms to all converge into a big mind grinder for propaganda.
In fediverse there is no valuation seeking to ruin things, and there won’t be for the foreseeable future, so it’s good ground to build upon, it’s just good sense.
Take the content problem for example. You can think of that as an opportunity to be the content you want to see.
