I just had the same issue. I made minor edits in the questionnaire and replaced it. An error appeared (something like assets not matching query). I tried to log out and log in again. When I logged in again, I realized that my project has become a draft, with no submissions. There were 500+ submissions before that. I can´t retrieve the data anymore. Could you please help out with this?
