The sequence of Instagram story views depends on the timing of when each viewer accessed your story. The ones who saw it earliest will be at the beginning of the view list. It's a straightforward chronological order.
Instagram's sorting of story views is based on a complex algorithm that takes into account factors like interaction, time spent viewing, and the relationship between the viewer and the poster.
Maybe your story isn't interesting enough or it's not reaching the right audience. You might want to try adding more engaging content or tagging relevant people.
You can check who views your IG story by going to your story and looking for the 'eye' icon or the 'viewers' list. Usually, it's pretty straightforward.
