Why has my AirPlay function randomly stopped working?

I have a 55” TCL Fire TV and out of the box the AirPlay function was fine. I could stream and mirror my phone display with ease because it connected to my home kit. For some reason this past month, the TV won’t even become detectable. When I try to go to the display settings menu for AirPlay, it does nothing when I click on it. I’ve tried clearing cache, deleting data, and unplugging. It worked once but it’s not working anymore. Any solutions or suggestions?
