Forced into redesign despite opting out

I have been avoiding the redesign and using the old reddit for years. Every once in a while it forces me into the new one, which I then have to go and uncheck. About an hour ago, it forced me into the redesign again but the preferences section was hidden. I had to guess the URL for it, check it again, select that I didn't want the redesign, but I was still in the new reddit. I am currently able to use old.reddit.com, which I feel like was disabled in the past (?) so I'm not sure if I trust that to stay active. What's going on here.
