Dscout payment question

Hey all, I searched this sub but didn’t find an answer to this.

I’m new to Dscout but just participated in a week long diary study. The study closed and the payment was shown as pending in my rewards tab. Now it is completely gone, the study is still listed as closed but the payment is not under the pending or paid section.

Are they not going to pay out for this mission, or do I need to continue to wait?
