Hi. Sorry to hijack this thread but I didn't want to open a new one.
I am trying to do the same as the OP but I'm unable to. My wife and I each have a smartphone with the Alexa App on it. My phone is able to 'see' all the devices we have. My wife's phone does not show any devices - when I go to add device (on my wife's phone) it takes me all the way through 'setup' and then the phone can 'see' the device but now on my phone, the device has been removed and I can't 'see' it.
Any thoughts / suggestions greatly appreciated.
