Hello guys, I was trying to use the screening based on participation on Prolific, but I cannot find it in the options anymore. Could you please tell me what is the issue there?
Welcome to the forum Yuri 
Add Screener > Participation on Prolific > Exclude participants from previous studies/Include participants from previous studies (in the latter case if you want to invite them back).
How’s that? I hope it helps.
Tim
Dear Tim, thank you so much! For some reason that option was missing, when I checked yesterday. However, I can see it now. Thank you!

Yuri,
I guess Prolific had issues with their database. I suspected that but did not want to come straight out with it without covering the obvious.
I also had a similar issue recently and thought it might be due to the fact that he study I was attempting to exclude was still “active” but that would not explain the absence of the whole “Participation on Prolific” section.
I am glad it has sorted itself out.
Tim
