Hi, I use official Objective-C SDK for the Dropbox API v2 with my app for iOS.
So, there is very interesting behavior - when I try to upload my huge files on Dropbox and at that moment I lock screen of my iphone (not "Home" button) - I get error from server-side "The network connection was lost" (-1005) and internal SDK error isClientError. As result my file isn't on Dropbox.
Any ideas about this case?
