I just got Quest today and was following the tutorial on the desktop app version, but do not have the option to list the contents of a container upon opening it like you can on the browser version. Do I need to update, or is there some way to fix this so this option shows up?
The options are all the same between the two versions. However, I believe the desktop editor has something called "simple mode" (or something like that) designed for beginners, which hides about half the controls in the editor (including that one).
I don't have the desktop editor to check (as I can't get speechsdk to run under WINE), but that might be your issue. See if you can find that option somewhere.
