I recently purchased a TCL Roku TV that supports AirPlay. I later returned the TV (in favor of a different model). However, the TV I returned still shows up in my list of AirPlay devices on my iPhone (and whenever I try to select it AirPlay says that it can't connect). The TV only show up on my iPhone and not my Mac or iPad. I only ever used AirPlay on the TV with my iPhone and not with my Mac or iPad, so my guess is that's why the TV only shows up on my iPhone.
I've tried the following to delete the TV from my iPhone:
Restarted my iPhone
Restarted my router
"Reset Network Settings" and "Reset All Settings" on my iPhone
Reset my iPhone's passcode and my iCloud password
Disabled "Automatically AirPlay to TVs" in Settings ---> General ---> AirPlay & Handoff
After trying all of the above, the returned TV still shows up in my list of AirPlay devices on my iPhone. Any suggestions on how I can get rid of it?
