Same for me. Some report this doesn't work but I can't confirm if they are choosing the correct settings as I have never had an issue with that even on multiple accounts.

It's useful if you use something like Firefox containers and aren't necessarily logged in when you visit a reddit link

I use the Multi-Account Containers extension [1] and make sure the "always with" option is ticked, so the browser will automatically switch to the right container, where the right cookies live. This said, obviously it doesn't work in Private Windows and it's indeed annoying as hell to use Reddit in that case.

they switch you back to the "new" design every day or so and you have to switch it again.

That's simply not true.

It does happen that you can have the setting on and them sending you to new reddit. It’s happened many times for me.

It did happen to me, but only a few times and it was transient, it seemed like the frontend can't reach the settings DB intermittently.

I'm really not sure if I can attribute Hanlon's razor to this. When you log in, that's by definition hitting the database, and should return your settings. Place that in a cookie/localstorage and it should still know your settings offline.

There is no single database at the scale reddit operates.

My bad, *a database.

I'm pretty sure I saw in an AMA that Reddit has an Accounts database (maybe split further by sharding) which I'd assume holds your settings as well.

But I rescind my point; it could very well be attributed to database infrastructure issues, whether that's hitting a shard with stale data, or splitting account settings to its own DB that it can't access when you log in.

at this point they should have those setting at an equilibrium
