sending videos direct to online storage apps (not iCloud)
I made a short illustrative video on my iPad2 that I wanted to upload direct to an online storage drive, OneDrive. I clicked the sharing button and selected 'other' and was only given the option of DropBox, which is also installed on the iPad.
Why did OneDrive (or any of the other storage drive options I have on the iPad) not appear under 'other' (or when I pressed 'more') when I selected the video for sharing? There seems to be no difference in the settings between DropBox or any of these other drives.
I realise there are ways round this (eg by downloading from iCloud then up to OneDrive) but I'm curious as to why the option isn't available.
Thanks
