Every single lesson in Lumio pops up a QR code to get the students to join. Not every lesson needs them to have their own tablet with the lesson in front of them. As a first grade teacher, I want their focus for our lessons to be on me, not on their own tablets. It is very annoying to have every single lesson, all day every day pop up this code. It should be optional for lessons that have activities in them, but not on every single one.
