@MABirdwatcher - Have you tried to change your device name to Sally in iPhone settings, check the app, and then change back to Sally's phone? Could you please attach a screenshot where you see "Sallyâs phone"? Thank you in advance.
@MABirdwatcher - My apologies, I thought you were having issues with the XFINITY Stream App. For the xFi App, this is a known issue for Apple devices. We are currently investigating the cause. I was able to duplicate this issue on my iPhone as well. Are you on iOS 11?
