The upload speeds are dreadful on iOS. The fact that I cannot select multiple files a or folders to upload to one drive is a killer. I have to load each file stored on my iPad or iCloud individually. I was wishing this would be a great alternative to apple iCloud. The only 2 benefits I see as of right now is I am able to stream my content without downloading and the previews of my content is displayed better than iCloud when browsing files. Upload speeds need to improve.
