If you open the chat next to the messages and you select one you have to reload the hole chat part to select an other chat partner.

Can you add a back button so you could see the previous chat list?


(Also I tried out on windows phone it was great altough it was a little slow when I opened espionage reports and wanted to scroll down)


Edit:
If the problem is considered in this section:
"Private Messge List - Missing Functionality"
then close it
