I paired my controller with my tv. I unpaired from tv now it won't work on x box

You have to re-pair it with the Xbox

Also ive had problems with my controllers randomly unpairing from my xbox and not wanting to pair back up. I had to switch controllers and when i swap back later it works again.

I have the same issue:

* the plain Xbox controller (non elite) connects via bluetooth to the TV and is recognised by the Xbox cloud app on my Samsung TV. I can use it to play games using the Samsung Xbox app.

* the brand new Xbox Elite Series 2 controller connects via bluetooth to the TV and is NOT recognised by the Xbox cloud app.

I tried several attempts deleting the pairing, re-pairing. Turn off TV on the power switch. Re-installing the Xbox app on the Samsung TV.

The result is always the same:

* The Xbox Elite Series 2 controller connects successfully to the TV and is shown as Paired and Connected in the Samsung TVs feature where you add external devices.
* But the Xbox app shows the yellow ! exclamation mark and does not recognise the Elite Controller.

I’ve paired my other non Elite standard Xbox controller now vie Bluetooth and USB, which works both.

Joe, I have solved this issue. Go here: https://apps.microsoft.com/store/detail/xbox-accessories/9NBLGGH30XJ3 and download XBOX accessories app. Then with a USB type C, which is what I use for my Samsung phone, connect your controller to your PC/laptop and open the app. The app will notify you that you need to update your controller. After the update I deleted all pairings between the controller and TV and started a new pair. At first the TV would recognize the controllers and give the message "need pairing" but the TV wouldn’t pair the controller. I did a hard reboot on the controller and a reboot of the TV and paired again and voil there was the controller paired to XBOX. I hope this works for you

I paired the controller to my phone and then unpaired it; it immediately paired to my PC via the Xbox Adapter. I've spent hours trying to get this to work, I really appreciate your help in solving it!

Out of curiosity I tried the same thing to get it to pair over bluetooth, but that didn't work.
