So I’m in the same boat but I’ve noticed an interesting dark pattern they use now to discourage old Reddit.
I often land in a comment section of a specific post, and then want to see more of the subreddit by clicking the link of the subreddit in the top of the page. Since about a month now, every subreddit shows me it’s only available through the app. I used to then preface the url with old. however now they’ve somehow done it that I will see the specific (locked) subreddit page, but the url will just be Reddit.com with nothing else, effectively making it impossible to add the old. before the url.
