There's no problem as such which was not being able to solve before I started using this. because there are tons of chatting applications for business purposes such as Hangouts, Microsoft Lync, etc. but now that we have switched from that to Whats App just to check it's versatility for business purposes. if we find any dislikes then we might switch back to hangouts. but apart from that, it's fun to communicate with colleagues with this app. Review collected by and hosted on G2.com.
