I use the ProtonMail and the GMail e-mail web applications on Ubuntu Touch. I want to download any files attached to e-mails I access using these web clients.
However, when I attempt to download an attached file like a compressed archive (.tgz) I am presented with an Open with page that states:
"Sorry, there aren't currently any apps installed that can handle this type of content."
I don't want to "handle" the attachment in any way other than to download it. How can this be achieved?
