A fair amount of apple services don’t “just work”. Signing iCloud out of every single device, and restarting can often fix this.

Really there’s a lot of reasons to say it’s bad and half baked. But the bones of it, clear two way communication, are not easy to do and I just want to praise them for that.

at this point it should never wear out, it life span is near forever for tech. 4k, HDMI, Wi-Fi 5, Etherne, the video Files are all going to still be usable and in use 20 years from now. its low power so I doubt heat will ever get to the components. Software support is up to apple.
it’s a luxury item, so most will get upgraded and sold/out of use in 5 years I think.
