With the latest iOS update (5.5.0), some screens were redesigned. I think most of this is for the better, especially since the new designs feature helpful explanations.
There is one huge problem, however: as far as I can see, it is no longer possible to check how many coins I currently have in the language. The Statistics screen only seems to show the lifetime coins total. But in order to know whether I can “save” a streak, I would need to see lifetime coins minus all the coins previously spent: to see if I have 5000+ coins currently.
I would appreciate if this vital information could be displayed again ASAP.
