Dear @raghu ,
After some investigation, it turns out that the problem is into the Google Play Services update - version 23.34.14 (190400-560151436) and later.
As a temprorary workaround, we can suggest removing these updates via Android settings (Settings > Apps > Google Play Services > tree-dots menu > Uninstall updates), as well as you need to restart Interviewer and Supervisor applications. These steps helped me and offline synchronization works fine on my devices right now. Feel free to provide us with new updates.
