I've just tried it with my Samsung (Android)...
During some minutes I tried to find out the "New posts" item. I failed ...
Then I tried to get back to the "classic" style. It was also hard enough: I had to scroll to the bottom, then click somewhere on the screen to let the small ads disappear. Only after these manipulations I made the forum interface more or less usable!
Unfortunately these "usable interface" and a "mobile" style appeared to be incompatible for me.
