So, have a bit of anxiety and am currently hiding EU threads until I can deal with it rationally.
Unfortunately, it's taking 3 or 4 attempts to hide threads on Active using the mobile site. I click hide, and it disappears, but then when I reclick active, the same thread reappears.
Not every thread, it seems to be sporadic and I'll get 2-3 that work then 2-3 that don't.
Sorry tech!
