Hi Daniel, I'm sorry to hear about this although the MWC winners were beautiful essays and I'm sure Medium wants these types of stories.
I love to write about writing besides my life as a mom, job as marketer and life lessons.
My idea for you: Becoma a Top Writer in #Fiction and try to write as much as possible to become one fo the Top 5 on the list. I'm sure you'll see results.

I have an online course where I help new writers. One of them is also a fiction authior from Spain. She also struggles with finding her path here on Medium.
