Creating a missing article almost immediately is met with an admin nominating it for deletion for something like “notability”, the catch-all term for “I personally don’t care about this topic, and if it was important someone would have made it already.”
If you survive deletion then your article is often removed from the main Wikipedia site into “draft space” where it is hoped you’ll just go away, with a reason like “need more than the X-number of existing <refs> you have.”
If you still haven’t given up trying to contribute it is currently a 6 week wait to have your article reviewed to be moved back into Wikipedia-proper.
However! You’ll find any fair-use images you uploaded to support your article (say a movie poster), well those have been deleted since “draft space” articles are banned from containing them.
Those are just some of the trials I’ve gone through in the last two months trying to fill in some gaps on Wikipedia. It feels like they’ve added so many layers of bureaucracy over the last decade even longtime contributors are being forced away.
