Apple TV 3 Airplay problem "Activation Failed" answered

Hi. I had this problem Apple TV 3 (A1427) Airplay no longer working. If you go to Settings>General>About>At the very bottom of the screen and you see the following "Activation Failed" then I may have the solution. It worked for me. I flashed the software via a Mac or iTunes and this didn't work. Reset settings, restored and tried different combinations of sequences and I still had the Apple TV 3 "Activation Failed" error message. I download Apple Configurator 2 for the Mac and set a new profile and after the second attempt I restored Airplay and had a working ATV3. Note: this only works via the Apple Mac. You may require a third-party app if you are on Windows or my need to emulate a Mac. I hope this works, as these are good devices. Oh, by the way, I also reset my ATV3 (A1427) back to the previous legacy build 8.4.2.1, as the latest build lost the Airplay functionality. I do not intend to upgrade further unless I have spare time as I don't want to have to rebuild it again! Let me know if this worked for you?
