Hello,

We have sent a tokenbased survey to about 6000 people.
So far about 1000 respondents completed the survey, about 400 completed only a part of the survey.

About 1 % of the respondents complained that they were asked to give a token at the end of the questionnaire (see screenshot). However, looking at the data, this seems to be on different pages in the survey.
Additionally, from the mails we receive from our respondents, we suspect there are considerably more than the 1% that send us a complaint/message about the problem.

What could be the cause of this?

Thanks in advance and best regards,

LimeSurvey version and build number ?
Plugins ?

Version 3.17.5+190604
I don't use plugins.

Not sure if it will solve the problem, but you are currently running a version of Limesurvey that hasn't been updated for over a year.

The current version of your branch is 3.22.20+200616.

When you update, update to this version (don't update to 4.x yet for a production environment).

Thank you for your response.
We'll try that.
