I’ve tried restarting everything and using different devices to do the continuity camera and it still stutters like crazy as of tvOS 17.0 on the newest generation of AppleTV 4k. The person on the other end of the call gets relatively clear and smooth video but on the AppleTV the video will stutter like crazy.
My AppleTV is currently not wired so overloading of the WiFi may be the culprit but somehow I don’t feel like this should be the case when the WiFi is providing roughly 1.8gbps currently with very little jitter or latency.
