Finally I solved all the sync and receive message only startup problems, it because the last seen .
If you used android whatsapp before, and set the last seen of time, status, picture to 'Nobody', then when you use Mitakuuluu, then you will get those sync and receive message problem.

It is a must to set those last seen setting to 'Everyone' in android whatsapp before setting up Mitakuuluu!
Now I have no any problems with Mitakuuluu!
