I have had Chromecast w/ GTV for 3 or something years now. I have loved it. No issues whatsoever. I used it at my nans for over a year with no remote issues at all.
Unfortunately my android TV projector I used at home stopped working so I got a TV out and brought my Cast home to use with my TV.
At first it worked fine. Then it stopped so I changed the batteries and still nothing. I put it in pairing mode and it said couldn't pair. I then reset the remote and it paired okay.
3 times since then (every time I use my TV) I have to re-pair my remote to the cast to use it. It's driving me insane because it was fine literally the night before. EDIT: Forgot to mention that the whole time IR worked okay. It's just Bluetooth.
Any ideas? TIA
