I'm also wondering why Web Files are not available. I'm trying to read a CSV file from a Bank's website to visualize exchange rate data, but the CSV file is a bit weirdly done. With Web Files, this can be done easily, but not with a REST connection, because the first set of rows in the file is blank. Web Files automatically ignore these blank rows and I get to the data easily. But REST gives errors because the format is different for some of the rows. So now I am stuck with only 2 options:
1. download the file manually and upload the file to Qlik Cloud;
2. read the file via Qlik Sense Desktop and bypass Qlik Cloud entirely, or manually upload the QVF file after a reload.
