Samsung TV UN65KU6300 Issue

So… I had the device connected and it worked for several months flawlessly. Then the device stopped working so I removed it. Now I can no longer re-add it.

When I follow the normal instructions through the ST app, 0 devices are found. Does anyone have a trick.

Samsung\Smartthings have turned that option off.

No one knows if they will fix the TVs with a firmware update. Not good
