Impact new chat icon on # chats

Since the redesign the chat comes with a new icon. We have the feeling that this icon generates less chats then the previous icon (at this moment we don't use the "show online status"

Our customer team made a note that they get less chats after the update.

Do other user expierience this problem? 

My feature request is the possibility to choose (and/or A/B test) different icons for the chat function.
