Doesnt Epic require marketplace content creators to update to a new version within 10 working days or face being removed? It comes under the sections of professionalism and is part of Epics quality assurance. Id definitely be contacting the marketplace people at Epic directly on the matter

It’s a 30-day notice, but there are multiple packs, even those who released half a year ago that are still not on 4.14 and that’s sad as we as Marketplace sellers get pushed to update quickly but seems tolerabele for other packs. Maybe it’s not tolerable but rather that the pack never gets reported, in any way @Author of the post, if after the 30 days the pack is still not 4.15 i’d say encourage the marketplace to take actions.
