The display name difference between Microsoft Teams clients
There is a difference on display name of a user between Microsoft Teams desktop client and mobile client. User’s display name is shown as a full name in desktop client. On the other hand, only the first name is displayed in mobile client. So, it would be great if you could standardize the display name between two clients.
+1 vote for customizing your display name... having the full first and second name(s) is a nonsense most of the times cause it makes messages harder to read.

Or even better, make it an option. Make the option settable globally, and per-channel. (Some channels may only have one "Mike" or "Alexei", other channels may have five or six.)
