Many annoying add-ons. Can't turn off or block challenges from people you don't know. It doesn't have a "teacher" anymore. It is difficult, if not impossible to switch dictionaries. Messages don't stay localized to one game. If you have more than one game in progress with the same person, you don't always know which game a message applies to. Chat has been dumbed down. You can't use special characters/imgs There should be an option to switch to a mode that behaves like the original Scrabble app.
