document that "Personalized Learning" forces phone app

I created a Kahoot (quiz type), then created a student-paced (homework) challenge assignment. I turned on the feature "personalized learning" because it seemed useful. However, as students reported, they were then not able to play on their computer. It required a phone app.

When I was creating the assignment, the pop-up "tool tip" (mouse over the "?") for this feature simply said "Players practice difficult questions after a live game." It sounded useful. However, I believe that forced players to use the phone app. Not all of our students have a smartphone!

Once a challenge is created, this option cannot be changed. Therefore, please document this requirement in the pop-up tool tip.
