I miss the app also, but I found several ways to go to the all unread threads, it is under the header “New” or “New posts”.@Vlad Not sure if anyone else mentioned but one thing I liked about app was it showed me all unread threads. I really liked that because I was more inclined to read and comment on active threads in forums I didn’t always frequent. I don’t see it organized that way without the app.
It is on the top left and also in the drop down menu.
