My daughter has an ipad 2 running on version 5.1.1,
When she tries to upload a video to her Facebook profile that she has made with the ipad video camera or the "videostar" app the upload bar reaches the end and then says "upload failed" . Photos upload without a problem. The Facebook app is up to date.
She has tried doing it through Safari but when she clicks on upload video the "search" button is greyed out and no video can be selected.
Her friend also has an ipad and has the same problem.
I have spent many hours searching for a resolution to this problem and tried things from privacy settings to uninstalling the Facebook app loging out and back in, doing a hard reset of the ipad but as yet I have not found the solution.
