Can't post on story (IG and FB)

[Adept_imagination0D44]

Can't post content on story. Content is 1080x1920px so the size is ideal for this contnet and meet the requirements. Adobe express have some issue with that so I have to make it by the Meta business scheduler

2nd issue:
Additionaly when I've made a animation for stories in Adobe Express, and want it to public over the social media accounts like IG, FB. I have checked to post on "Story" in options. The final result was that Stories was published on Instagram corectly but on Facebook it published as a post in timeline.
