After the most recent update to the Interactive Legend instant app, when the option Interactive legend open at start is disabled the legend still appears when the map is opened. This is not the expected behavior from the previous version.
Also when the app is embedded in an iframe that has a width less than 950 pixels it forces the legend to be expanded and take up the bottom third of the map. It would look nicer if this didn't happen, and the legend was just collapsed (this seems to be new behavior too).
I submitted a bug report but did not hear anything in back. This broke some of the previous apps that we had created.
