Hi, I have a survey with more than 19.000 participants and we have around 9.000 responses. All participants have a token and first name and the survey is not an open survey (participants must enter a valid token to do the survey)

In the responses table I have 15 responses (only 15/9000) without token and firstname.

I don't know why this is happening and how I can assign a participant to each of these 15 responses.

See attached a print of the response table with one example and the csv export.

Did anyone have the same problem? Or any idea how to solve this?

Thanks a lot

Anna

Possible issue in this version .

It's a "don't use in production" version …
