downloading "larger" courses to iPad
I have found that downloading a "larger" course to the Ipad ( larger means 10 Mb or above) is often problematic. When I choose the "Available off-line" option, the download bar occasionally halts and then I get the message that a file is missing , which is not true (everything is on the server). Usually after trying again one or more times, it all ends up working.
But at other times, videos that should appear in a lightbox slide don't work (probably because they did not get downloaded).
Has anyone experienced such issues?
Any ideas what may be causing this ( server performance/overload, insufficient bandwidth?).
Thank you in advance.
