An issue in the chat history of the new Spark 2.9.0.
If I’m John Red (username in AD = email@example.com) and I open the chat history with Mary Green (username in AD = firstname.lastname@example.org), I see all the messages of Mary Green with the right name Mary Green, while I see all my messages with email@example.com.
No problem with Spark 2.8.3 (I see John Red in all the lines).
THANK YOU VERY MUCH for this new Spark release!!!
