UGC Post Image media order not respected - linkedin

Question

I'm creating an UGC post with mediaCategory IMAGE and multiple images attached uploaded with the recommended Assets Api.
I've noticed that LinkedIn does not respect the original order we are sending through.
Has anyone experienced this as well or has any idea what I'm missing?

POST https://api.linkedin.com/v2/ugcPosts
I think you want to maintain the order of media in single post.
But I see same media ID "media": "urn:li:digitalmediaAsset:C5500AQG7r2u00ByWjw",
5 times. May be it is just a dummy message.
I think you should try get on it
GET https://api.linkedin.com/v2/ugcPosts/{encoded ugcPostUrn|shareUrn}?viewContext=AUTHOR
and you can see media order. I think media order stays same. It is just how LinkedIn is displaying it.
