I tested this and am also able to see a problem similar to that reported by @Brianc:
- when user card direcory enabled
- visiting user directory
- select Message button on a user card
- not taken to the new message composer, the avatar and username disappear from the card
@moin you haven’t provided enough information for me to understand what you are reporting in User Card Directory: message button should not show on mobile. Are you talking about something else?
