Looks like you have wazapp hanged coz of plenty of chat history which takes a lot of time to load once you launch the application while showing connecting on the top, i faced a similar issue yesterday, Just follow these steps which i followed and it solved the problem for me. FIrst of all, just wait for sometime with the connecting status on top then on the same screen after some time then delete the conversation which is very long ,then after some time it shall display a message "application not responding, Quit application" click yes on that. Restart your phone after that then just click once on the wazapp icon and wait for it to load ! Sometimes it hangs due to launching the application multiple times while it is being loaded. Hope it helps
