Thank you for reporting this issue with the existing My Cloud Mobile App v4.1.3 for iOS.
Western Digital has begun to slowly roll out the latest firmware for our MyCloud product in support of the new My Cloud OS 3 operating system.
Once fully rolled out, MyCloud OS3 will support such features as a Software Developer Kit (SDK) enabling enhanced app integration, a more intuitive user interface delivering a rich content-sharing experience, and back-up and sync capabilities that elevate the personal cloud NAS offering while retaining the privacy and control unique to personal cloud devices physically located in the home or office.
WD will have these new features available for customers on the latest code late September of 2015.
