Hmm I'm not seeing that message, though when I turn off bluetooth on my phone it doesn't connect anymore, so it must be using BT then.
All is working fine for me now, not sure what's different about my setup compated to others. I do occasionally get disconnected (it happened just now) but I'm not sure what's causing it. My TV turned off out of nowhere just now, right after turning it on, I think it might be CEC. Right after it turned off homekit was reporting 'now response'. But after I started it with the remote everything worked fine again.
