Wazapp does not work very well for me at all. In fact, it's barely functional. Half the messages I receive, I can never read. If one clicks on the "Chats" tab, half the conversations are invisible (just totally blacked out and unselectable). I can manually select the contacts in question by going through "Contacts", but I only see the messages they sent prior to this bug occurring, not after. Once this bug hits (and it seems to eventually for all conversations), the only way to 'fix' it is to uninstall Wazapp and reinstall it. If I'm to understand correctly, this is a known issue?
