When someone is rejected, the system will ask you to put a rejection reason. This is helpful for all teams to track, and we recommend.
We don't have a way to turn this off explicity yet. For now, you can just click cancel or press escape when you see the modal! If you want to completely hide it, you can always unmark the Rejected stage option next to the Rejected stage. This will tell Stardex to not show the rejection reason modal. This may impact your tracking
