www.progress not working

Hello,

www.progress is not working when I download a video from a server and I am using any iOS device. It always returns 0.

If we move the video to another server, it works. Besides, and strangely, it works in the unity Editor in all cases.

I suppose there is a difference between the two servers, in their settings or something. We check the size of the video to be read and seems to be ok.

Any help will be appreciated or at least any hint ..

thanks in advance
