As i didn't recieve any answers in the 'intallation and updates' forum, I'll try to X-post here.
My question:
By default, when a user (respondent) saves a survey, he gets redirected back to the active survey. Our test-panel found this confusing. "I want to resume later - why am I taken back?". Therefore we have implemented a redirect. After a users saves a survey, we will not redirect them to the main page (where they came from).
Hoverever - sometimes when testing the "Resume" functionality, the saved survey is empty, i.e. the user clicks the links sent by email - the survey opens but with no answers registered from last use.
This happens inconsistently - and maybe once every 8 or 9 tries.
The survey is not very big, but e.g. the first question is a multiple choice question with 100 checkmarks.
Since the error is inconsisten I would very much like to know, if anybody has hints to what could be causing this situation. One of the answers is prefilled via URL btw.
