My Automatic Airplay Sent Adult Content to Someone’s Smart TV but I don’t know who’s

I recently moved into an apartment complex with a universal WiFi system for everyone in the complex. Earlier I was viewing some questionable adult content on my phone when I noticed the blue glowing AirPlay symbol at the top. I have never used AirPlay before so I didn’t think much of it. Out of curiosity I recently checked my settings and saw that automatic AirPlay is turned on??? I am pretty sure that somebody was subjected to what I was watching. Just hoping it didn’t display my full name along with the video to their smart tv :)
