If you open Standuply app in Slack, first thing you see is Home tab and a list of reports.
Some of them are created by you, some maybe the reports you were added in:
If you click Actions button, you will be redirected to Partial answers page, where you can give partial answers to a report ahead of time or run a report manually/ pause on you. edit, if you are a person who created report.
If you switch to Messages tab, you will see report's which you gave answers to. Questions arrive at time scheduled.
