This is a feature for iOS and iPad(latest firmware v11.4, server v5.0.0), I’ve requested a long time ago. I was very excited to hear it would finally be implemented in the next MM iOS client release(v1.9).
Now it’s out and it’s not working most of the time and not fully implemented.
For iOS or any other platform to fully support files we need three things. 1 send files(upload), 2 get files(download) and 3 view files (file preview).
So when uploading files, most of the time it fails, clearly a bug. You select the file but it doesn’t upload to the server with the following error. (notice that the file contains a reload icon but clicking on it doesn’t do anything).
There isn’t a download button for most of the file extensions. There is a toolbar with close button on the left and download/share on the right side. The download button should alway be available no matter the file extension. (notice at the top, for this file (a picture), the download button is available however in the next screenshot, for a text file, it’s not available).
Most of the file extensions don’t have preview. movies, documents and so on. (notice in the screenshot, a text file is selected and no preview).
