Any time I add a new contact to my Google contacts, the second I turn on my WiFi it gets disappeared. It's been for over a month on Android 4.3 and 4.4 I have tested. This is new and I have not had this before. I guess the problem lies with the synchronization with Google account.
Note that this is not the case with Phone or SIM card contacts. That's why I am sure the problem lies somewhere in sync.
Is there any official issue that I'm not aware of?
