Over the past few weeks, my Apple TV has performed terribly. I get the spinning wheel whenever I start a movie or tv show (purchased through iTunes). Today, I sat through an entire episode of GOT where the picture never cleared up. Here are the specs and what I've done only to find the problem persist. (1) Internet speed test from a computer in another room: 315Mbps(upload)/277Mbps(download). I have a fiber optic line directly into my home. (2) Apple TV 4k Version 11.4 (3) 2160p UHD-60HzHDR-10 (4) Internet wireless router is less than 6 feet from Apple TV (5) No gaming (none in the household) or downloading of files during these periods. Trouble shooting (1) Restart Apple TV (2) Forgot and rejoin wifi network (3) Reset and Restore Apple TV (4) Update Apps (1) Netflix (2) Reuters (3) Vimeo (4) HBO Prior to this, I found that the more clips I watched on Vimeo, the more buffering would occur. Also, the more trailers (via iTunes on Apple TV) I watch, the more buffering. After the 2nd or 3rd trailer, the loading bar just stops. I would rather wait for the episode/movie to load and watch it in UHD, then run it at a substandard quality. Any suggestions would be greatly appreciated.
