I am a substitute teacher, and travel around to different schools. Last week, I worked at a school and connected to an Epson projector via Apple TV (Airplay) and screen mirroring.

Yesterday I got a message from the teacher I subbed for - she said that her projector was showing my screen and it was "moving around." I asked her to send me a photo, and the projector was showing my iPad screen from the previous day. The fact that it was "moving around" sounded like it was showing a screen recording of my activity on my iPad after I had turned the projector off.

She said she restarted the system but it is still showing my screen. Any thoughts would be much appreciated! I can't understand why it screen recorded me in the first place! And why restarting is not helping. Does she need to do a complete reset?
