* Mobile version hid the chat and everything.
* It was not clear how to start video chat.
* Audio wasn't working at all, even after 10 minutes of trying to get it to work (permissions were granted). At this point I'm not sure if it's a feature or a bug.
* Half of the apps aren't available.
I'm sorry, but in the current state it is not usable for me, or anyone I know, at all. Compared to whereby, hangouts, etc I'm not sure which currently existing features it really offers that are better.
