How to download from iCloud?

[l_g]

I downloaded an mp4-file that plays fine on desktop VLC. Now I want to access it on my iPad. First I set up an iCloud account (saving Pages documents to this account works fine between my iPad and my Macs) added two folders, Movies and Videos (Google returned different suggestions what the "correct" name should be, hence I tried both). Finally I copied the mp4-file to both folders.

iOS-VLC can browse this account and can see both the Pages documents and the mp4-file (in both folders), but when go the left hand pane -> Cloud services -> Cloud Servies (yes, I have to tap it twice) -> iCloud Drive -> Movies -> my movie.mp4 the spinning wheel appears for 10 seconds, it flickers a bit in upper left part of the "window list" of the Movies folder and then I am thrown out to VLC's "All files" Media Library with where it just says "Empty media library".

Am I misunderstanding anything here?

The movie is 1.4 GB, I have an iPad Mini 3 with all updates and plenty of empty space, 100 MBit network and AC WiFi.

Bump..?

I can't be the first person trying this, can I?
