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.

I’ve heard editing comments is likely more effective, but it’s hard to say. I’m guessing they take regular backups anyway, so maybe that’s not really a thing anymore.
Regardless, I’m planning on replacing all of my comments with something like “screw you Reddit, use Lemmy instead” or something to that effect. I have a ton, so I’ll need a script to do that, which will probably get blocked anyway.
