On a Windows 10 Mobile, Lumia 830, with lhe Windows app (moodle Mobile 1.13) I can log in to my courses and see the contents on them. The problem comes when I try to download anything: either it is a .pdf, a .jpeg, a .doc, my Lumia always gives the same information: I have to download an .app to open that file. If I try to download one, I always get .php editors.

Thanks
