No, it doesn’t have buttons like that. Here’s what I see (attached).
I also just noticed that there’s a yellow frame around the CODAP window (inside the browser tab). I don’t know what that means but it seems like it might be relevant.
It just occurred to me that it might be my ad-blocker, AdBlock Plus, but then I turned it off and tried again in that window and the dialog box for sharing still didn’t have the enable-sharing button. But now I’ve tried opening new windows, uploading the local file, and then sharing, and the dialog box _does_ have the enable-sharing button. This is all in Chrome, in case that’s relevant.
Thanks,
Andrew
