I have been having some frustrating issues with my ATV4k and have been unable to come up with an answer to my problem. My ATV bricks up when I use it in 4k hdr and 4k sdr mode. When I go to open up apps, I get the spinning loading wheel and nothing happens. All other apple devices (Iphone, Macbook pro, ATV3) are connected and working fine with the internet. The ATV4k says that it is connected and has a great wifi signal. I am still getting up to 45mbs speeds but ATV4 does nothing. As soon as I switch the ATV4k into 1080p hdr mode, everything functions 100% normal which leads me to believe it's not the hdr but the 4k somehow. I don't really know where the issue lies. Router? ATV4k? It is connected via wifi, not a hard connection to the router, I would really like to avoid a long ethernet cable running through my house. If I restore the ATV4k back to factory settings I am able to operate in 4k HDR for a day or two, sometimes not at all. I have had ATV4k since Christmas and have done a factory reset about 10 times. Anyone else with this issue?
