Unable to add member to private channel

[melblanton14]

I was able to add a Member to a team, but unable to add her to the private sub-channel.  Help please!

Are you an owner of the private channel? Any specific error message you are getting?

I am the owner and experience the same problem. Windows app and web based app on Windows both fail in adding the member. When entering the name, or e-mail address, program will report "We didn't find any matches". Can add that same member via the Android app... seems like a bug to me?
