my last FIAS app, which has been created with 15.0.3, can't download and install files from cloud services.
When I'm in the file manager of my app and choose the button on the top left I get to my iCloud files (or if I choose Dropbox from the locations lists to my Dropbox).
I can choose a file, it is downloaded from cloud, but I can't find the file in the file manager of my app.
What is getting wrong?
Thanks for your help.
