This is great too! I don't see this option in the latest TestFlight iOS app yet, but I do see it on the server, and I set it to Current Collection. In the iOS app, I now see it set to "current-collection" and it's grayed out (as expected.)
But it doesn't appear to be working, at least in the Quick Guide. With this setting, I'm only seeing one channel appear (the thumbnail of the channel I'm currently watching) when I swipe down to show the Quick Guide. So I've changed this back to the (local) Favorites, for now.
Ideally I'd like to have the option to choose a specific Channel Collection as our default these options to use. For example I created a "Favorites" Channel Collection on the server to replace my local favorites. I would like for that Collection to source the channels in Quick Guide and Channels Surfing, regardless of what other Channel Collection I might have started off in.
This feature is an absolute game-changer and it works brilliantly with all the custom channels (i.e. Pluto) many of us have added recently. A thousand thank yous to the Channels developer team! This is yet another home run!
