Ever since the most recent update (yesterday), I can't turn Teacher off. I've tried uninstalling and reinstalling.
Same for me. This inane update makes for a major irritant. What idiot forced this down our throats? Makes you think twice before updating. And the Help is completely inaccurate: it says to click on the "Teacher" to turn it off. You cannot click on it because it does not exist except immediately after inputting a word. And then clicking on it DOES NOTHING. So the EA geniuses can really be proud of themselves; they've created a major irritant which cannot be corrected.
Yeah, this is really irritating. I've stopped playing because I noticed that friends were playing the word the teacher had just suggested for me in the previous turn. If I wanted to play the computer, I would. Maybe I'll go back to Words With Friends...
