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.

Honestly this is so absurd it’s funny. Peak business brain to think that people in 2023 are willing to download an app and register an account to simply access content.
Some of the Reddit community is outright hostile to the fediverse and decentralization in general. Apparently the lot of us are too nerdy over here.
I am absolutely fine with that crowd staying far, far away from us. If they like where Reddit is going, fine, by all means let them stay there.
