I am using version 0.8.9 from cepi. Whenever I have more than 10 chats, Wazapp randomly crashes on receipt of a few messages in wuick succession. Then it does not start up. To get it to start without deleting the DB again, I have to disable internet connection and let Wazapp settle for some time , before I switch to its window and then delete a few chats . This process too is long as I can delete only one chat before it crashes again ( without the internet connection) . Once the number of chats is below 10, its stable again and I can let on the internet connection and Wazapp behaves normally. I initially thought that the crash was when I got a group message when I had more than 10 chats, but seems it will crash even with normal 1-1 chats when I have more than 10 chats. Apart from this one, Wazapp behaves just perfect for me. I can send pictures, location etc without any issues. Hope this info helps.
