So I too had two phantom devices. So after reading what was described above I tried it and as you said it no longer works. So I tried a new variation and it worked on both of my phantoms. I had an extra receptacle that I made sure was not in my network by trying to removing it using the app removal process as described above. I than created a new device (called trash) with the type I know that is would used by normal pairing process (for my receptacle) plus of course the phantom network ID. (Now the change. Using the app on my phone I did a “replace” on the trash device. When it asked me for the new device I triggered pairing on my unused receptacle and it replace the phantom to the newly pared working receptacle device. Than using my phone app, I removed the trash device (which was a working receptacle). I re-ran Network repair and the phantom is gone. Doing it for the second phantom was the same process. Both phantoms are now gone and I have a clean Repair.
