Since my AppleTV 4th gen upgraded itself to tvOS 11.4 (overriding my setting of no automatic updates) I am having a very noticeable issue of network speed through wifi. Executing the Speedtest app in my phone and on the AppleTV I get aproximately half on AppleTV of what I get on the phone. Distance to the router is the same in both devices. Has anyone else had this situation? I’m considering downgrading the FW but not sure it is possible.
