Just got my Apple TV 4K and was treated to a message that "you may not be able to stream 4k videos because your speed might have dropped below 15mbps" The only problem is that my speed averages 50mbps, and when I check my speed at that time it was 48. Sure enough, 4k streaming has looked absolutely terrible, not even sure if it's streaming in HD. Right after, I tried streaming the same apps and shows using my built-in Samsung apps, and they streamed in crystal clear 4K. Everything on the Apple TV 4K seems incredibly slow, including Amazon/Netflix apps populating images, and loading videos. It can't be my internet connection given that my Samsung apps are lightning quick and playing in 4k. Does anyone know what would be causing this issue?
