This is only a minor issue but thought I would add it while Spark 2.6 final is still being built.
When you rt click on a user in the contact list and select “View client version” a Windows 7 computer is getting recognized as a Windows Vista computer in the operating system field.
I think it’s just that I am using spark 2.6 and all other users are using 2.5.8. You can’t replicate the issue because everyone is on 2.6 RC1. So it’s gotta be a spark 2.5.8 thing not a spark 2.6 thing.
