Hi, Kasper!
I’m unsure if there is a more tech-savvy answer, but one of the things I did was post my drafts under private where only I can see them. They will show up when you are trying to determine the aesthetics of your theme. Once done, go to the private post and either edit from there or click on “Revert to Draft.”
Hopefully, this will help until you are able to view drafts!
