We have discovered that students have found out how to turn off the Pin needed and authorization needed to cast to the boards in the settings on the board. Since they can turn this off they can randomly cast to the boards with their phones and display whatever they like. There is also no way to lock the settings that we have found to keep them from doing this.

I have also learned that the Smart Remote Management can't control the screen share access. This has turned into a huge liability that we can't control.
