It would be really useful if we had a feature that allowed us to schedule a time in which a public release would be activated (IF it passes moderation).
If an update were to get approved after the scheduled activation date, the release would be automatically activated as usual.
Right now, we only have the option to auto activate public releases as soon as they are approved, which has been very useful. Therefore, I don't see why this feature isn't already available in the Creator Portal.
