I noticed this behavior. When using ClinicCases over the mobile interface, documents on the case home folder are not displayed. Documents are only accesible if they are located inside a folder.
Also, PDF files cannot be opened or downloaded on the mobile interface. PDFjs viewer is not displayed and console show this message:
Resource interpreted as Document but transferred with MIME type application/pdf: "https://casos.likeweb.mx/lib/php/data/cases_documents_process.php
It would also be nice to add a download option to the document context menu. Is there any way we can do this? Would you prefer if I open another discussion under feature request?
