> It's usable on all platforms except iPhones and Apple TV where we're forced to use HLS at higher Latencies for now and hopefully later also DASH or LL-HLS once that's reliably usable.

Interesting, since it was Apple who designed & built both the original HLS and the LL extensions. What's currently preventing LL from being usable there?

Their initially released specification depended on some relatively impractical services being provided by the CDN. In following revisions that was improved, but last I checked the major CDNs still didn't support it. I think because it still requires much more from the server side than DASH and struggles to reach comparably low latencies. In the mean time people like us have started to work around it to get DASH support in iOS instead.
