People please stop SPAMMING about connection issues and that Wazapp closes itself read the previous pages damn....... I will write once more how ti fix these issues. Do this when wazapp closes it self: Disable all your network connections and then start Wazapp up (i think you have to many chats, i had the same issue) with all network connection disabled you will have more time to delete some chats before Wazapp closes. After deleting some chats start it up again and it should work. Or just delete the .deb file and reinstall it! Connection issue Wazapp keeps connecting. Do this: Sync all your contacts after a few sec you will get a message Wazapp does not react do you ant to close it yes or no, press no it will finish syncing then restart Wazapp and it will work again! I hope this is clear so there is no excuse anymore to spam here about these issues over and over again.
