Usernames fault? does not support uppercase nor underscore


I can not create a username in the My Cloud Nas, for instance like “Peter_falk”

Does not keep uppercase and as soon as an underscore is included it fails.

This is really anoying since it worked perfectly with other WD NAS such as My World Edition or  My Book Live.

How can faults be reported to get fix in future firmwares?

Open a tech support case.
