Screen Mirroring

It seems like this issue first came up in 2015. It is now almost 2018, has there been a fix to enable Screen Mirroring on a 2nd Gen AppleTV from an iPhone running iOS 10 or newer? I would like to stream apps such as DirectTV, or Spectrum Cable, or even some horse racing apps like TVG or TwinSpires… Any suggestions??

yeah, super annoying. I am just replying to add a voice here.
