On Step 4: no chat is visible

[fipsofant]

Hey!
I have followed the tutorial till the end of step 4 (chat view and send messages).
But unfortunately I can only see the chats but chat, and view and send messages I can't.
So I downloaded you Ionic-MeteorCLI-WhatsApp-step3.zip and created a new folder and installed the missing packages via "meteor npm install...".
Finally the built succeeded but there are no chat view too.
After the "meteor update --patch" it said that underscore is deprecated.

Maybe there is something old, not working anymore in the code?
