Hi there!
I was asked if there is a way to lock down an iPad setting under Settings --> General --> other languages so that a student can NOT select and change the language on his/her iPad.
Once the student adds a language, he/she can go to any website and select the AA in the URL bar, and from that menu, toggle back and forth between as many languages as they add.
Our Middle School Students are causing a ruckus with this.
From what I can see, it's not something we can do, but I know if anyone knows it's someone here!
