Version 5.6.11


      1. When answering on an iOS device, there was a problem where the "Next" and "Result" buttons would not scroll to the position where they were displayed, so it has been fixed to scroll automatically.
      2. In the case of fill-in-the-blank quizzes with partial points and multiple holes in one question, there was a problem that partial points were not scored even if the scoring button was pressed when some holes were filled with correct answers and others were left unanswered.
