Last night kodi was working fine on my Apple TV 4 and the next morning when I try and open it. It says kodi is no longer available? Anybody else get this?
Was Kodi ever actually available in the mainstream Apple TV store? Generally it has to be installed on a jailbroken Apple TV or via a semi complex process of manually signing the app and then sideloading it to your device via developer mode. It is NOT an easy process. Although it CAN be done with proper instruction.
So you signed it with xcode etc? Perhaps something got messed up with your installation. Did you do a Apple TV firmware/OS update? You might have to delete Kodi and start from scratch to fix it.
