I looked at all your articles since Jan 11, barring one 7 min read (i think on Meghan Markle, Jan 12) all your stories are 2-3 min reads. Medium explicitly in their distribution guidelines has now said those don't get curated. Their sweet spot is 4-7 min, longer get some love too. And the delay in curation is par for the course these days - I have articles taking 4-5 days but do get distributed eventually, and the slightly lower rate of curation is happening too (I've gone down from 80-90% to ~50ish i'd say). Your issue however at first glance is length of article. Some places, size does matter it seems haha
