Hurrah, my app has finally updated.
I followed Quisling's instruction for "anorak" and did get 'cagoul' and 'wind', so no problems there.
However, I'm not entirely sure what the point of, or how to use the "and, or, not, second term" option.
Plus, if I put in "object" which is the definition of 19d in today's Guardian Prize, I reach the 500 limit - none of which contain the answer But, Also, if I put in the answer instead of "object", I do get words like 'demur' 'disagree' etc., but still not "object".
Am I doing something wrong?
