Currently whenever a quiz has manually graded questions (e.g. essay questions), upon submission students immediately see either a zero or the current score for the graded portion of the quiz when they look at their grades on the mobile app. This causes great confusion because they have no way to tell whether the quiz has actually been graded or not. Although the preliminary grade may not be calculated into their course grade, they don't actually know that.
Please fix this for the mobile app in the same way you have fixed it for Canvas online, by covering the score for an ungraded quiz with the quiz icon.
