yeah, good for us to compare notes. I've taken Prolific surveys in the past month just fine. Emailing 'requesters' on Prolific, when you have no history with them... is a little mysterious. I dug around looking for an easy option to email them, and clarify what they were looking for re: Device Compatibility... then decided to abandon that non-paying task, and hunt for tasks that do...That's weird. It was just a typical survey. Not sure why it would screen you out.
