Yes. Once a survey closes, Macorva EX reports are immediately available to view, segment, export, etc.
We do, however, recommend implementing a "quiet period" when building your survey. This is a short window of time (usually 1-2 weeks) between the survey close date and the date when survey results are released to employees. This gives admin users and company leadership time to process the results, review key findings with your Customer Success Manager in your survey report-out, and create a message and strategy for employees outlining how you plan to act on the results.
