I think this is limitation by the browser to prevent spam. What you can do is put all the pdf’s in a zip archive and download that. Check out https://appstore.home.mendix.com/link/app/323/
Is it perhaps similar to the Showpage-activity. Meaning it only starts at the end of the microflow (or transaction) and therefor only runs it once, for the latest DownloadFile-acivity.
Try this using a submicroflow for the DownloadFile-acivity (or in the loop use EndTransaction widget, but IMHO that’s dirty and don’t know what happens with it in a loop)
Thanks Guys for your help on this.
@ Andrej, I downloaded the zip module from the app store and applied that as per your suggestion - It worked great!
Thanks for the idea. :)
