Apple announced that the first developer beta version of the upcoming iOS11 is available. Seeing as this is in the beta stages, downloading it is not necessary for anyone else but iOS developers. The reason why is because many apps will not work with the upgrade until it is out of the beta stages. One of those apps is DIRECTV NOW.
DIRECTV NOW will cease working with the iOS11 developer beta update. This includes on Apple TVs, laptops, iPods, and iPads.
Although DIRECTV NOW will not reap benefits of this beta update, Apple TV itself will. You can sync the home screen of your Apple TV across multiple Apple TVs. There is also a light and dark mode in this beta developer update.
