On Joplin Android, when I open a PDF attachment with an external editor (Foxit PDF, Xodo), make some changes to it, I cannot save the attachment. Both editors complain that the file is read-only. It seems that Joplin lets the editor cache the file, but then the editor cannot return it to Joplin. Is this expected behavior or some limitation of Android (sandboxing)?
I've also tried other file formats, such as pptx, but these are read-only as well.
When I checked the permissions for Joplin Android, I noticed it had no access to the file system, so I gave it permission but it had no effect.
