The old iOS app accepted one of multiple words or sentences in a multi-item-answer, style: home,flat, apartment, cottage, digs.
The resent iOS app requires you to know each one, even worse, in the right order. This makes it close to hopeless to finish most courses as in addition to knowing four or more synonyms you also need to know the order of these listed.
Please put back the old behavior of accepting one of multiple entries. What I have to do now is to in and remove all such entries which is tedious.
