Junk app. Does not work with pixel 4 pixel 6, old iPads and does not give me an option to add a device on my surface pro. May be time to move to a different brand of devices for the home. Have reset the tv I am trying to add. Deleted and reinstalled app on 3 devices. Nothing will get past registering the device. Clearly a software problem. As the pixel 4 is 2 years old this would seem to be deliberate. I am done with Samsung.
