Basically only the communities in another language, I don’t have any issues with it, other than not wanting to translate news articles.
I do have one user blocker that is a troll or bot that is constantly posting political stuff, something like 30+ posts a day and nearly 80 comments a day, most of which are down voted to hell for obvious reasons.
I had this exact same problem using Firefox containers, if you try and open Lemmy.world in a container it logs you out every time you close the page or browser, I just started opening it without assigning it to a container and it seems to work just fine.
