For a few hours now, I have been systematically getting an error message for surveys in which I prescreen with the option “Exclude participants from previous studies”.
Whenever I explicitly select a previous study whose participants are to be excluded from my current one, I get an error message when I finally want to “publish” the study. The message reads: “Sorry, we’re experiencing some issues. Please try again. If the problem persists, please contact support.”
This error does not appear when I do not use this prescreening option.
I get the error no matter what previous study I chose for exclusion. As far as at least one previous study is specified, I get the above error.
Unfortunately, I really need to use the above prescreening option for my upcoming surveys.
Can anyone tell me whom I can contact to get help?
Thank you very much.
(Just to clarify: I have been running many similar surveys of this type on prolific over the last years. So, in principle I know how to configure my surveys.)
