I have opened a webapp I built with web AppBuilder, made some changes and want to save them but cannot find a way to do so. On the bottom of the left hand panel is a banner with "Launch", "Previews" and "Saved". Next to "Saved" is an upward arrow with options to "Save" (greyed out) and "Save As" (see attached). I've tried saving as a different app but the changes did not stick. Am I missing something?
