The third beta of tvOS 10.0.1 is already in the hands of the developers and like the version of iOS 10.1 beta, it is polished with the passing of the days and the existing beta. On the iPhone if you will notice a change since the beta adds the novelty of portrait mode for the iPhone 7 Plus. But let's leave aside the beta for iOS and let's focus on the beta of the Apple TV that adds few changes after the previous beta 2 in which we saw the arrival of universal searches in Spain and Mexico.
This time it seems more like a beta with few changes in this regard for Apple's set top box, but it does add bug fixes and fixes to previous version issues. The details of the news are discovered as we access the beta, Apple no longer explains the news of these versions, so if any outstanding news appears we will make an article for it or simply explain it in this.
If you are using an Apple TV 4 that has already received the second developer beta the third beta should be available as an OTA update. If, on the contrary, it does not appear automatically, you can use a USB C cable to connect it to the Mac and download the update.
