Video and image preview takes ages before being available. Only option available is to download the file.
Video streaming stopped being immediately available after the upload for both videos and photos working.
I tried to make sure it wasnt a codec problem by copy n pasting a video file that is showing the preview. When I paste it it stops showing the preview. This is not a codec problem, it's exactly the same file in the same folder.
In fact after several hours the preview was available (like 3 hours after the upload)
