In Classic quizzes, the number of points would automatically update based on the point values in the questions I added.

However, this does not seem to happen in the New Quizzes.  It stays at "zero" (the default) regardless of the actual point value of the questions that are added.  This is true even if the quiz has been published.  I can of course update the value manually, but that's a bit annoying and I will be sad if this basic feature (which had been in the older version of Quizzes) somehow doesn't work in the New and Improved Quizzes 😉 ...
