Hmmm that’s too bad.
Final update: an empty array did not completely work. Somehow leaving it empty made it impossible to actually publish the post (status remained “draft”) so I filled it with some dummy text and now it does what it should do. This issue must be somewhere deep in the WP code.
Really not happy about the fact that I do not understand why it works because I have the feeling it will bite me in the ass at some point, but at least it does work.
Thanks for the help!
