Tested on Staging iOS version 1.12.4 (24-327)
Tested on Staging Android version v1.0 (413)

Steps to reproduce:
1. Go to a common with transaction e.g. "emc common"
2. look at the transaction line

Actual results:
the user name contain only first name

Expected results:
user name must contain first name and last name

Reproduce the issue by opening a common with a transaction, such as "emc common," on the referenced staging iOS or Android versions and inspect the transaction line. Trace the UI entry point that renders the user name; done means the line displays both the user's first and last name.
