Qlik Cloud has ability to export apps (download them) with and without data, but there is no way to download single QVD file. It's a bit confusing.
For example, I've received invitation in my company to join one of the spaces and I had to get data from single app to perform my tasks (some training). But I couldn't manage to download single QVD file. All I could to do was export the app with data and perform extracting with Binary Load into new app and store the table into QVD file.
So my idea is simple: please add ability to download QVD file from Qlik Cloud.
