"Pending" means your points are under review until the date noted in your All Earnings page. It may take up to 24 hours for points to post into a pending state. The pending state for surveys can take up to 14 days. After we have cleared your responses with our research partners we will mark your Points from "Pending" to "Approved." You can find the date that your Points will be approved in your All Earnings page.
We have to wait until our research partners give us the all clear on the data provided in order to release. This is generally a regular practice and happens on all studies.
