It is a worest app after the last version of it. It's includes a bug where you unable to restore your data, and if you could by somehow to return all the messages, after awhile it will logged off and ask you to restore again and unable to restore your data. You will lose all your messages and the restore will happen daily. Thats shame.. I hope this bug will be fixed as soon as possible othewise, the whatsapp is useless and has to find an alternative app.
