It’s been 4 days and we still don’t have an answer. The really frustrating thing is that until we are sure that after 21 days we will be able to publish our maps, we will not be able to continue with our projects given such uncertainty, since there is not even any information indicating that this problem when publishing islands is due to not having 21 days in Unreal Engine.
The problem publishing islands is widespread, even with people who have map creator code.
Epic, hurry up please!
