This behavior has been resolved and deployed to the production environment in version 2.2

Description

Scrolling through New Quiz submissions on the teacher app for Android is slow and laggy, additionally it is too sensitive to left/right swiping and keeps switching to the next/previous submission while attempting to scroll up/down.

The Android teacher app should provide a smooth scrolling experience for New Quizzes the same way it does for other assignment types.

No workaround exists at this time.

  2. Take it as at least one student.

  3. As the teacher access the course on the Android teacher application.
