How to see whether interviews "Started" but were not completed?

It seems that the server never sees interviews that were “Started” but not completed. Is there a way to see this action?

In which mode are the interviews collected?

The interview mode is CAPI

Interviews that are not completed are not sent to the server from the tablets, because, well, the interviewers are still working on them.

Please read about partial synchronization.

But I believe that one can still see if interviews have been started but not completed by mining the detailed action logs.

I believe I started down this path in the past. I’ll be sure to share anything I can find from previous efforts.

Detailed action logs may reveal only the fact that the interview has been started, not the data in it.
Unfortunately, the user @nkaralashvili wasn’t clear about what she wants to achieve with that.
